Too bad about this project - I thought it would be hard to achieve but that didn't affect my decision to back it. Since it won't be completed, I should get my money back soon so nothing was lost for me.
I think a keyboard project should have good backing opportunities. Either just new key caps for existing keyboards in various colors (I think many would like black keycaps so they don't have to raid CDTV keyboards) or complete replacement keyboards for 500/600/1200. A compatible mechanical keyboard would be cool (if it can fit inside).
