Having been able to look at all the infomation etc, I really don't see this being a success or something I'd ever want. The idea is interesting, but the way Nintendo have implemented it is just poor. Nintendo just don't seem to get it, do they? They keep trying to find a market that simply doesn't exist or has moved on to other devices that are far easier to use.
Ah well, here's hoping the eventual drop to third party doesn't hurt them too badly.
