PSP!!!! i loooooveeee my psp!! the graphics are soo much better too! its like a mini comp too you can store your music and listen to it aswell as pics andvids its really good and pluusss theres loadsa good games on there
Dunno what your interests are...but I picked DS bc I LOVE mine and play it way more than my PSP...here's a small breakdown
PSP (New: $169.99 MSRP) better graphics, more "traditional" gameplay. Internet Access. Also plays computer media transferred onto the memory stick. Recommended for gamers who love racing games/ action games (like gta)/sports. Has some decent RPG's, but not too many. My biggest complaint about this system is how tiny the library is...but what it does have tends to be more substantive. My favorites on there: LocoRoco, Patapon, Valkyrie Profile: Lenneth and FFVII: Crisis Core
DS Lite (New: $129.99 MSRP) graphics aren't as good and no internet access. Less traditional gameplay via the touch screen; also plays Game Boy Advance games. Recommended for gamers who love RPGs, platformers (a la Mario), and puzzles/logic puzzles/point-and-click mystery games. I have a ton of games for my DS, and the library is HUGE compared to PSP, but there's a lot of games that aren't very appealing unless you're >10 years old. My favorites: Zelda, Mario, Dragon Quest, Professor Layton, and Phoenix Wright (all are series).
DSi (New: $169.99 MSRP) Same as DS Lite, but add a small goofy camera, internet and media access via an SD card. Take away GBA slot. I have both of these because while I wanted a DSi I couldn't justify getting rid of my DS Lite for it.
Feel free to message me if you have questions. I work in a game store so it's kinda my job to be knowledgeable.
psp, because i'm a playstation person. better graphics and games than DS (except kingdom hearts 358 2 days ._.) online access c': <3 looks cooler and more futuristic. you can use it for all kind of media ^_^
PSP because it's made for more of a videogamer. It has a lot of good titles. Can also be used as an MP3 and video player, and has very impressive graphics.
DS is more for older and younger people. Only has a few good RPG's on it. DS hasn't got online access, the last time i checked anyway. It also hasn't got as much capacity as the PSP's memory stick duo's have.
Lol, i used to work at a game store, so sorry if nothing's correct. i'm out of touch XD
