here's what I think.
Try a PSP, Honestly, there is a reason why only 12% of PSP owners own a DS, because once you go PSP, you won't go back. ;)
PSP give you PS2 graphics on the go, if you are a HUGE Metal Gear fan, go with PSP..
if you want to play same games you played on GBA (or GB for that matter,), a game with almost identical engine from 10-15 years ago, Buy a DS and get your Pokemon Pearl. ;)
