Reasons you're wrong
1. The DS relies on cartriges to minimize loading times. Since when was the last time you saw "loading..." on a DS?
2. I don't need my DS to watch movies. I have a dvd player. I don't need my dishwasher to cook dinner, I don't want my slippers walking the dog, and I don't want my brain deluding me into thinking that useless features like that are worth...
3. The price. DS? about £50 from a shop nowadays/ PSP? About £150
4. Graphics. Yes, woo, the PSP's graphics look better. But you made the DS look bad by stretching the two screens out of proportion of the one-screen PSP. And at the end of the day, it's a handheld, I don't care about the looks, i'm not that shallow.
5. Games. This has been mentioned before. The DS has LOADS of great games, mario kart DS, rayman DS, wario ware touched, new super mario bros, project rub, mario 64 ds, and many, many, many more. What do we have on the psp? the same kind sh*t the ps2 offered us with worse graphics.
6. GBA games. The PSP can play gba games if you download an emulator. The DS can play gba games. The GBA can play gba games. The gameboy micro can play GBA games. BIG WHOOP.
7. Wifi. Suure... whatever. You can play crappy games on a crappy console with a slightly superior wi-fi caipability. I've been using DS wi-fi for a long time and I haven't found any problems with it yet.
8. The PSP can update itself. What does this mean? It means sony can get away with releasing a flawed handheld just because they can make changes after it started being sold. The DS was perfect right from the start.
9. Features. So the PSP has a little analog stick and side buttons and all the usual? The DS has a touch screen and microphone, bitch. Both work very well. It's reached new areas of gaming. The PSP? Tried and tested.
Sure some people prefer the PSP, and i'm not going to judge them. But most of the people who like the psp have not tried the DS. I have (regrettably) tried the PSP. It was clear how bad it was from the moment I put the UMD in the wierd, tape player like, loading mechanism. Now look, i'm not a nintendo fanboy. I bought a PS1 and a PS2 rather than nintendo. But the PSP is really terrible compared to the DS. Who knows, maybe after the gamecube and the N64 nintendo are moving forward more, with the DS and the WII! SMD ya $600 ps3.
