It will be quite funny to see people who liked the DS as opposed to the PSP because it was just a game machine and claimed they didn't need anything else change their tune and speak of how awesome this new DS is.
Bet Sony and Apple are shitting bricks right now. I suppose Nintendo does know how to lay golden eggs. If this works with memory sticks I might be considering a DS. How much does 20,000 yen equal in US dollars?
