"Wow, it's soooo long!"
Don't worry, I'm on about a PSP. But yeah, no way in hell could you get this comfortably in your pocket. The good thing though is that nearly all of it is screen. However, you'd be a madman to carry it without a case, bumping the size up even more. I had a quick go on Metal Gear: Acid, but it was terribly uninspiring. I have to say, it was very smart, but simply too big, it really does push the word portable to the edge.
The DS has so much more going for it: pictochat, 2 screens, extremely low price, strong launch title selection.
Norky's prediction for the year: PSP will fail. Too expensive, too few quality games, too big, arse battery life.
