two questions regarding the DS and the DSi

[nintendodork]

PSP is good for homebrew/hacking
And one of the few reasons I have a PSP is to play Katamari
But I still recommend the DSi or DS because of the Flashcards, or with the DSi, SD cards also that let you play virtually any game available behind the N64
Plus..Sony stole several games that were previously released on other (Nintendo) systems
