I have a DS although I want to get a PSP because it has a wider range of games in the genres I like and it has better graphics. The DS games are more interactive. DS all the way!

It's sad.
The question was "Which is better?", not "Which do you prefer?"
Even the OP responded to the wrong question.

In terms of power and capability I say the PSP wins, it may not be an easy victory, but it definitely crosses the line first.

PSP has the XMB (XrossMediaBar)- easy access to any content (video, music, game, friends..etc)

In terms of graphics, SONY wins this as they have with current-gen consoles.

Games - This one goes either way, really. DS has classic games as the Mario series, Zelda, and the ever-so-popular Pokemon games. However, the games on the DS are more fun-oriented games. They lack the emotion bond found in such games as Crisis Core: Final Fantasy VII (anyone who's beat the game knows what I mean.. some man-tears shed during the last cut-scene), God of War: Chains of Olympus.

Network capabilities - I would argue the PSP takes this one, too. Granted wireless play between friends is easier with DS right now, as ad-hoc (?) isn't currently available in the US, but the ability to search the web, and to wirelessly connect to the PS3 (if you have one) and stream vids and music and view pictures stored on it is a note-worthy feature.

Up-coming games - I don't claim to keep up with DS releases but this year is looking promising for the PSP, Rock Band: Unplugged releases this year, ad well as LittleBigPlanet and Assassin's Creed 2 will be finding its' way onto the handheld. The Duke Nukem Trilogy, Gran Turismo Mobile, and this next game gets a sentence all to itself. Dissidia: Final Fantasy hits the US this Summer.

So, yea, overall I would say the PSP is Better, technically speaking.

If anyone has a different outlook, feel free to (intelligently) re-butt anything I just said...

*If anyone wants specific sources feel free to request them (or Google them), I don't feel like finding links for all these now.

*interesting tid-bit, I own a PSP and my gf has a DS, it's quite the interesting relationship....lol

i love the ds! exspealy playing CoD world at war! (call of duty)

I played CoD4 on the DS, honestly it wasn't that bad..
I prefer the console version, though.

oh.. sorry for the inappropriate intro and poll.. gomen..

dont be too hard on yourself hikki, this was a great thread, keep up the good work!

thank you ^_^

I have both a PSP & a DS. & i prefer my PSP.

in the same way that the wii doesn't make a better console than the PS3 just 'cause it has a wii-mote, the touch screen of a DS doesn't make it better than the PSP.

people keep whining about how the PSP doesn't have much games for it or whatever, then go use pandora on it. it'll give you a wider selection of games.

personally, I play my dsi more, but after a while I want to play some larger games with better graphics like gta:lcs (shame mine got stolen :( )
