Jeje Dunno, maybe because i hate Mario and Nintendo don't have good fighting games.
It's my opinion

I pick DS. It just seems to have more fun games.
What's the point of getting a PSP if none of the games interest me. ._.

Nintendo DS. Im more of a child at heart Also I can't resist the Mario Bros. games so yeah.

Why do we need a PSP when there is a PS2/PS3

DS will be my choice..

There are a lot of things that would make a gamer buy either system but heres what i think of them
Nintendo DS
This is a system to play all those crappy nintendo 64 games on with a different type of gameplay
with the o so cool touch screen to change your experience of gaming but i don't think Nintendo utilizes the touch screen
to the fullest of its capability. But mostly the DS is a great handheld for any age because of the vast amount of genres of games on it.

Sony Play station Portable
This system is for more mobile gamers that can stand the crappy overview in almost all the games other than turn based rpgs(final fantasy battle style) but this isn't only for gaming it is basically also a mini computer that can play music and view pictures and browse the internet if available. Also has the great feature of playing whole movies on it which in theory is saving u money if u want a portable dvd player but a portable dvd player cost mayb 100-500 depending on specs batery life and stuff like that and screen dimensions but the psp makes you buy a different format dvd disc. so basicly ur not saving any money
but i like the psp for hardcore gamers that like time consuming and non arcade games.
this system is for hard gamers not little kid gamers

That's harsh. Back when the N64 came out, I thought they were the coolest games ever. [Okay, I was eight.]

BTW, I voted for the DS. The touch screen is just too cool.

I would have to go with DS because it has the touch screen to play mini-games, and its a whole crap load cheaper

I chose the PSP because of the graphics,it can be updated to several versions,but its also easy for it to get destroyed,I almost did when my dad gave me one for christmas.

The PSP is extremely boring.

The DS isn't a bad console, I'ved enjoyed a few games on it so far... like Animal Crossing Wild World. (that just makes it the best handheld ever. XD)

The DS by far. The touch screen HAS to be the best feature yet (next to the Wii of course).
