Design of Sony PSP
From an aesthetic perspective, the Sony PSP is a gorgeous device. It's one of those gadgets you immediately want to get your hands on but vigilantly want to protect once you set it down. Weighing essentially the same as the Nintendo DS (6.2 ounces, including removable battery) and measuring 6.7 by 2.9 by 0.9 inches (WHD), the body feels well built and solid in your hand. Although not a lightweight, it's by no means a brick, nor, we suspect, would it be especially durable in a fall; you'll want to treat the PSP just as gingerly as an iPod or a Palm-style PDA.




The centerpiece of the handheld is its especially impressive 4.3-inch wide-screen display (480x272 pixels, 16.77 million colors). The screen is flanked by controls that will be immediately recognizable to fans of past PlayStations: the directional keypad is to the left of the screen, and the familiar square, triangle, circle, and X buttons are to the right. We dug how Sony managed to include an analog "joystick" below the directional keypad. The stick isn't raised like the analog controls on a PS2 or an Xbox, but it conveys that multidirectional element that gives it a joysticklike feel.



In lieu of the PS2 controller's four total shoulder buttons, the PSP has two: one per shoulder. Ergonomically, the device is OK but not great; as with most handheld gaming devices, you'll have to do a little finger stretching every 15 minutes or so to keep from cramping up.

The PSP uses Sony's recently created "cross media bar" interface. You use the directional keypad to horizontally navigate through Settings, Photo, Music, Video, Game, and Internet icons, and each section has other icons attached to it on a vertical axis. All in all, it's a simple and elegant way to access the PSP's many features.

Games and officially licensed movies come on Sony's proprietary UMD (Universal Media Disc) media, which are housed in protective cartridges. The UMD drive is grafted to the back of the unit; you load it and snap it shut just as you would a camcorder. The top edge also sports infrared and a USB 2.0 port that you can use to link the device to your PC or Mac, though no USB connection cable is included.



The headphone jack is at the bottom left of the unit; Sony's official earbud-style headphones sport an in-line remote to control basic playback. The nice thing about the remote is that you can use other headphones with it, not just the provided 'buds. Like Apple, Sony has chosen to go with white headphones. We're not sure why, since the PSP is black (though an iPod-white version is available in Japan).

One gripe: Since the device has a glossy finish--and is mostly black--it's a fingerprint magnet. A static-free cloth should always be at the ready when using your PSP, and the Value Pack had one bundled. Sony's official carrying case is a padded soft case, but a variety of third-party versions are also available (see our list of PSP accessories for more information).


Features of Sony PSP

The folks at Sony tout the PSP as, first and foremost, a gaming device. But in the next breath, they claim that it can do so much more, billing it as "the first truly integrated portable entertainment system." Both statements are, in fact, true, and suffice it to say that as a portable gaming device, particularly from a graphics standpoint, the PSP is unparalleled. You're getting a miniaturized PS2 gaming experience--or close to it, anyway--and Sony has amassed a decent selection of titles from various game developers to show off its handheld's gaming chops.
Beyond gaming, the PSP's video prowess may be its most impressive trait. As we previously noted, the display is a 4.3-inch TFT LCD with a 480x272-pixel resolution and 16.77 million colors; by comparison, each of the Nintendo DS's two screens has 256x192 pixels with 260,000 colors. The picture quality from a UMD movie such as Spider-Man 2 is superior to what you'll see on most portable DVD players, though the majority of DVD players have significantly larger screens.

The only problem with video playback--and it's a big one--is that it's currently hard to watch anything but UMD videos on the PSP. Unlike Sony's MiniDisc, UMD is not a recordable storage format, so you'll have to store any video or music and images on a Memory Stick Duo card. The lack of affordable and recordable UMDs has put the format in dire straits. Sony is hoping to give the format a boost by bundling UMDs with its DVDs and creating an accessory that can transfer the video to TV, but it remains highly unlikely that the many studios and retailers that have jumped ship will come back.

Thankfully, getting media onto a PSP is much less of a hassle than it used to be. The Sony Media Manager software lets you transfer photos, music, and videos from a PC to your PSP with relative ease. It also lets you back up your saved games and manipulate podcast feeds. It's a worthwhile alternative to the bare-bones media management options with which the PSP originally shipped in March 2005, but it will cost you about $25--it's not bundled with the PSP. Fortunately, there are also a wide variety of third-party and freeware software titles available, many of which focus on converting existing video files to PSP-friendly formats (see our "How to put video on your PSP" tutorial for one example). Unfortunately, "home brewed" videos are limited to scaled-down resolutions that fail to completely exploit the PSP's native 480x272 screen. The exception: live, streaming video from Sony's LocationFree TV accessory. This Slingbox-like device lets you watch live TV on your PSP while in range of any Wi-Fi hot spot. Still, it's a shame that the only way to take full advantage of video on your PSP is to buy UMD-format movies or expensive networking accessories.



What about music? Well, the good news is the PSP plays many types of audio files without your having to convert them to Sony's proprietary ATRAC format first--a common problem with the company's earlier MP3 devices. You simply drag your audio files into the music folder on your Memory Stick Duo card, and they'll show up on the PSP. Firmware-updated PSPs can play MP3s, ATRACs, WMAs, WAVs, and AAC-encoded song files, though not the copy-protected versions from Apple's iTunes Music Store. The device supports M3U playlists, but if you have your playlists in another format, you'll need to find and download a converter. However, as basic as the PSP's music player is (read: iPod Shuffle with a screen and no autosyncing capabilities), it will be adequate for many people.

Those interested in replacing their iPod with the PSP will have to deal with the lack of on-the-go playlist functionality and, most important, the DIY storage. You can get a 1GB Memory Stick Pro Duo card for about $50, while double the capacity will cost you about three times as much. Sony announced 4GB and 8GB Memory Sticks at E3 2006 but no pricing. Player controls can be initially tricky--the in-line remote is handy--but we like the speedy precision of the fast-forward/rewind functions as well as the undulating background graphics. The PSP can also display album art when it's available.

The image viewer is also basic, with simple slide-show functionality. But again, it's easy to drag JPEG files--or TIFFs, PNGs, GIFs, and BMPs, if you have version 2.0--onto a memory card, rotate them (if needed), and show off your shots to anybody who might want to see them. In addition, you can set a photo as your PSP's background wallpaper, replacing the colorful splash screen behind the home menu. Unfortunately, you can't view photos and listen to music simultaneously.

Last but not least, the PSP has built-in Wi-Fi capabilities. Getting our handheld up and running on even a WEP-encrypted home wireless network was a breeze, and the PSP lets you save multiple wireless configurations so that you can connect from multiple locations without repeating the setup procedure each time. Though PSPs purchased before September 2005 were previously limited to WEP encryption, upgrading to v2.0 firmware adds support for the more secure WPA-PSK standard. Once you're Wi-Fi enabled--and you've installed the latest firmware--you can access the Web using the PSP's onboard browser. This slick, nearly full-featured app supports tabbed browsing, Javascript, and CSS, though Flash support is still lacking (read more about the PSP's Web browser).

The browser looks great, displaying crisp images and reproducing colors very accurately. Typing isn't quite the pain it could have been; Sony has augmented its standard cell phone-style input system with a few shortcuts, giving common strings such as http:// and .com their own keys on the virtual keyboard. Furthermore, the PSP remembers every address you type, so you'll never have to tap in a long, complicated URL more than once. You're given the option to reshape the browser's display window, in much the same way that you can resize video clips during playback. This helps avoid the dreaded left-to-right scroll-back while reading articles, though it usually garbles the page's layout in the process. You can easily save images from the Web to your Memory Stick Duo and subsequently use them as wallpaper on the PSP's main menu; customizable wallpaper is another perk of the 2.0 firmware.

JavaScript works like a charm, cooperating with several JavaScript toolkit utilities, but the Flash player included in the latest update is version 6--the current standard is 8--which makes viewable content hit or miss. Our videos and the rotating feature images on the CNET main page, for example, require version 7 at the very minimum. On the PSP, the Flash images and movies change to text and still images, respectively. Some sites seem to mix and match Flash versions, which makes compatibility even more haphazard. We were psyched to see a Strong Bad e-mail start up, only to stop playing when the scene changed. We also noted that the Flash player struggled to work with compatible content, as Strong Bad's typed response chugged out in full words rather than the smooth tapestry of letters that normally flows from his laptop. Adding to the Flash woes is the lack of a suitable keyboard emulator on the PSP, rendering most Flash games unplayable.

As expected, overall Web performance is a little slow. On CNET's reasonably fast connection, we still had to wait a good 5 seconds before images started popping up on the pages. Once the images began to load, the cursor would freeze in place until they were finished downloading. This sort of thing isn't a problem on a computer, where you can still read plain text and click links without images, but the PSP's small screen made the wait a bit more frustrating.

The PSP's strong slate of features--as well as the many bells and whistles that Sony has added via its first major firmware update--proves that the handheld is still under development and hints at even greater things to come. Some of those future upgrades are more fully developed than others. Sony highlighted a few of the more noteworthy forthcoming PSP features in the pipeline at a business conference in March 2006. In terms of gaming, an emulator is being developed that will allow the PSP to play digitally distributed (that is, pay-per-download) PlayStation 1 titles. Later in the year, Sony is pledging to add Voice over Internet Protocol (VoIP) support to the PSP, with an EyeToy-styled Webcam peripheral to complement it. A GPS-locator accessory is also in the works, with compatible games slated to support it. Finally, Sony is said to be preparing a major upgrade to its Connect online service that will create a more iTunes-like music and movie download service, but details remain scarce. In fact, since these new features were announced, Sony's been mum about new details--the camera was shown off at E3 2006, but no new information has been revealed about any of the other new PSP concepts. It's more than likely that Sony is waiting until the November release of the PlayStation 3 nears to comment on most of them, as it's likely that numerous features of the next console--accessories and downloads, among them--will be shared between the two.


Performance of Sony PSP

The Sony PSP runs on a proprietary 333MHz processor and comes with 32MB of built-in memory, some of it reserved for the PSP's operating system and applications, and 4MB of embedded DRAM. While we would have preferred more built-in memory, game developers we spoke to were happy it has what it has, given that early rumors suggested Sony would include only 16MB of RAM.
One of the issues with using an optical disc format such as UMD as opposed to Nintendo's flash memory-based cartridges is that load times tend to be significantly longer. After we previewed beta versions of games, we were concerned that load times would indeed be a serious problem. But now that we've run graphically intensive games such as EA's Need for Speed Rivals, Konami's Metal Gear Acid, and Sony's Twisted Metal Head-On, we can safely say that it's a relatively minor hindrance. Yes, games can take a good 10 seconds to load, but it's not much worse than what you'd expect from the PS2 itself. (As one might expect, content loads very quickly from a Memory Stick Duo card.) That said, the Nintendo DS and the Game Boy Advance SP are much zippier in this regard.

Luckily, the wait is usually worth it because most of the games look spectacular. As we said, you're getting close to a PS2-like gaming experience, and many of the titles are ports of their PS2 counterparts with only small compromises made to the graphics. For the most part, games play smoothly, though you may encounter some frame drops in bigger action sequences in certain games.

We played Twisted Metal Head-On against four other players in multiplayer peer-to-peer (PSP-to-PSP) wireless mode and were impressed by the smooth gameplay. We also played Twisted Metal via the Internet with two other people and had good results. But we imagine that when you get up to a dozen players (Twisted Metal supports up to 16-player multiplayer), you'll probably encounter a hiccup or two. And, of course, wireless gameplay depends on your connection--or, in the case of peer-to-peer action, the distance and potential obstructions between devices. As far as distance goes, we were able to move about 60 feet apart with a clear line of sight in an office setting before our connection became spotty. We felt the Nintendo DS offered better wireless coverage.

Before we get to battery life, a few sentences about the PSP's audio. Using the earbud-style headphones, sound quality was fine with games, but we would have liked the maximum volume to go a tad higher when we listened to our MP3s, especially in noisier environments. When you play games and watch movies such as Spider-Man 2 on UMD, you can boost the volume a bit via a special UMD volume-settings menu, which is helpful. A few preset equalizer settings (Heavy, Pops, Jazz, and Unique) are on board to tweak the sound, but you can't manually set treble and bass levels, which is too bad. The PSP's external speakers can't put out booming sound, but they're certainly adequate for gaming and casual video watching; using the headphones, however, will give you a much more immersive experience. Conveniently, volume can be raised and lowered from two buttons just below the screen or via the headphones' in-line remote.

Battery life? Well, a lot of numbers have been bandied about, with some critics suggesting its relatively short run time would be the PSP's Achilles' heel. Here's what we got:

Running on full brightness, we managed about 5.5 hours of gameplay before having to recharge the included 1,800mAH lithium-ion battery pack; gaming time can vary significantly depending upon screen brightness (two dimmer settings are options) and the game you're playing. It's worth noting that recharging a battery to full capacity takes a lengthy 2.5 hours. Playing in peer-to-peer wireless mode reduced game sessions by a little more than 2 hours; the battery pooped out after 3 hours, 15 minutes. For music only, the PSP was able to run for a decent 11.2 hours.

And finally, we managed to watch Spider-Man 2 all the way through twice and got 20 minutes into a third showing before the battery died. All in all, that's not too bad and slightly better than we expected. Still, the easiest way to ensure that your PSP doesn't go dead at an inopportune moment is to purchase an additional battery pack; kudos to Sony for making it replaceable. Transfer rate over USB 2.0 to an inserted Memory Stick was a reasonable 2.2MB per second.
