Isn't that pretty, $800 dollars worth of hardware. XD
Both me and my brother own a DS and a PSP (as you can see). So I'm speaking from example.
Buy a DS, it's that simple. But if you'd like I'd give a few reasons to go with a DS over a PSP.
PSP:
MP3 player ~ If you got an iPod or a computer that has your music on it then don't worry about buying it for that.
Movie player ~ DON'T buy it for a movie player if you got a DVD player. The UMDs (the discs for the PSP) don't hold as much as a DVD, so you'll be getting less stuff then what you would have on the DVD. On top of that, why would you want to watch a movie on that screen if you could watch it on your TV?
Pics ~ You got a computer, why put the pics on your PSP?
So it comes right down to games. If you know of some good games you'd like to play on your PSP then go out and get one. But for me if I could, I'd go back and smack myself and stop myself before buying the PSP (and my brother would do the same to himself). I spent $250 dollars plus a $40 dollar game and I get no use for my PSP. I turn it on maybe once a month, and I haven't played that game in 6 months or more. So as you can see I get no use out of the PSP for what it's real reason is (a game system).
DS:
Games ~ What else can you judge the DS on? Maybe lack of graphics (as in next to the PSP), but graphics doesn't make a game fun. Pong was a big hit, Pac-Man, Donkey Kong (the first game Mario was in), and others were great great big hits yet the graphics were bad. The games were fun and that's what mattered. Same with the DS, I got 3 DS games all are really fun. I got them because they looked fun, not because it has great looks. To me the DS is way way way way............. ahead of the PSP on good games. Not only me but most DS and PSP owners will say the same, and also game sites and shows (everything from GameSpot to IGN to X-Play says the DS is more fun then the PSP).
If you want game play then go with the DS. But if you have to have all them other things then go with the PSP. But before you buy one look at the thing you should be looking at the most. The games, if you find games you like on the PSP then get it, same goes for the DS. You're buying a handheld game system, not a home entertainment package. Yes most everyone that owns a PSP (who doesn't own a DS) says "The PSP rules!!!!!" mainly because you can watch movies, play songs, and view pics. I own both, and I've been on both sides (I've said that the PSP is way better then the DS), and I'm telling you, if I had to pick one I'd pick the DS.
