Other than DSi ware, is there really a need to buy a DSi?

[NintendoMan]

I am buying it for the larger screens/improved speakers and the addition of DSiCamera and DSiSound and the enhanced wireless of course. Oh then there's the new UI which is just plain better, the ability to 'hot swap' and the more comfortable stylus. And having had a chance to go hands on with an imported one thanks to a friend I also want the more comfortable stylus and slightly better d=pad, shoulder buttons & volume controls. Also something about reduced weight and thickness.
