this is a good site i found on the web..

go ahead and have a read..

personally, i prefer psp because it has most of the games i want to play..but psp 2 is coming out soon..at least according to the rumour..

then..do you intend to use ur dsi's extra features if you buy one? go and have a look at those funky features of dsi..this shud help u to narrow down ur choice..
