If you can wait, I'd do it. I'm looking into the Nintendo DSI, which is a new version of the DS.
The only bad feature I can see about it is that you can't play GBA games, or games with Guitar hero and like attachments. It has a built in Camera and and SD memory slot. It also has an option to sync with the wii.
I just saw it today in an Nintendo Magazine.

They don't have any colors availible at present other then black or white, but I'm sure skins will be availible soon.
EDIT: Also, from what the nintendo article said, it has a different type of surface, that prevents smudges more then it's counterpart. The Camera is also able to upload it's pictures onto the wii. I'm not sure if that information is on the wiki article, I only skimmed through it to make sure it was what I was talking about.
