i currently have the old fat ds and an R4. i use my ds mostly for reading and games. now im trying to decide whether i should get a psp go/psp or a DSi/DSi XL with a new mod card (can someone tell me what would be the best one for a DSi?) i like the graphics of the psp but is the gameplay good? ive only had a ds and im losing interest in the games that are out for it. im only waiting for the new pokemon game and thats it. i need a recommendation of games that will keep me interested if i decide to get a DSi. also im wondering, is there a homebrew app for the psp that will allow me to read ebooks?
