Conclusion

The PSP’s screen is simply amazing. It’s the first thing you’ll notice when you boot it up for the first time, and it’s the thing that will have absolute strangers eavesdropping over your shoulder while you’re playing (or watching) on the train. It’s bright and sharp, and minus what seems to be a somewhat isolated dead pixel problem, it’s practically flawless.
The PSP won’t be fetching sticks anytime soon, but it’s easy to see how this thing could replace dogs as man’s best friend. Imagine uploading your favorite team’s latest game or episodes of X-Play to the memory stick, and then watching at your leisure. The picture and video viewing really spark the ladies’ plugs, as well.
The way I see it, the only big mistake with the PSP’s hardware is the use of the UMD (universal media disc) medium. The loading times on this thing are ridiculous in some games, and pretty bad in most of the others. The UMD simply can’t stream information to the hardware fast enough.
