I've been eying all the different slot1 solutions, and I can't really make up my mind. Is it just a decision as to which sticker on the cart you like best? I've pre-ordered the DS-X, but since it hasn't been shipped yet I have time to change the order. I think I'll do fine with 4Gbit, and I don't already have micro SD's laying around to use in R4, SuperCard, EZ Flash etc etc. "Supports rumble pak and memory pak." Does DS-X have support for these? If the memory pak some day actually comes to use with any games that will be quite an important feature. Edit: hmm, I might have read a little too much into "supports"... that can probably be fixed with a future upgrade in the DS-X... right?
