The screen is as huge and clear as has previously been supposed, and the general feel of the hardware is top-notch. With that said, the analogue stick could be implemented a little better, we feel. It doesn't always stay comfortable to use for prolonged periods.
The games are PS2-quality, which is frankly astounding for a handheld console. It kicks the Nintendo DS into a cocked hat.
The video playback is also exceptionally good, and the PSP makes a great portable media player. The MP3 support, however, is pretty atrocious - the playback app really isn't particularly user friendly. Even when playing video, you can get a good 5-6 hours of battery life out of the unit.
The UMD disc format is pretty intruiging. It's clearly just a mini-DVD, but the plastic caddy makes it a lot more rugged - perfect for portability.
