En IGN ya tienen PSP: Impresiones

And the screen is indeed bright and good looking, regardless of battery or AC. We can't stress enough how good looking the screen is. We notice it every time we play the system, and we wouldn't be surprised if it's the first thing the general public will notice as well when looking at the PSP for the first time. Using the PSP in public is going to get some serious looks, and maybe even sell the system on some people. Being able to see such high quality visuals, in games or movies, is even more alarming given the price and compact size of the system.

We've already commented on some of the games from our playtests earlier in the week. We'll repeat ourselves here, with some added emphasis given our extra playtime: if you absolutely don't want to buy the PSP, don't look at Ridge Racers. The game is so gorgeous, so far ahead visually of everything you've ever seen on a portable system, that it'll bring out the graphics freak in you

We were able to put the WiFi features of the PSP to greater use via a quick test. We played Ridge Racers with three people and, similar to our two-player test from earlier in the week, found it to be a lag-free experience. In terms of range, we got cut off once we'd exited the Starbucks and walked a few meters away. We presume the glass surroundings of the building didn't take so kindly to wireless signals traveling between them. The best part about this was that there was no set up involved; we simply started up a wireless multiplayer game and had others join in, and that was it.

Playback of MP3 files is great on the PSP. We tried a number of files, from classical violin solos to some of Utada Hikaru's smoother tracks, and the sound quality seemed to be at top level when heard through our Nude EX headphones. The sound is deep and with just the right amount of bass, resembling Sony's MD playback, and even matching the playback of the more critically acclaimed MP3 hard disk devices such as the iRiver. If you have a large-enough Memory Stick (and even our 512MB stick may be cutting it close), the PSP could make for a cool music device.
