BTW, I'll add my vote for Scratch. Also, Mindstorms is intended for ages 10+, of course that may be adjusted down with mechanical *and* language giftedness but I find it's more than what my 7yo is comfortable with. There is a simpler LEGO product called WeDo for ages 7-12 (http://www.legoeducation.us/eng/categories/products/elementary/lego-education-wedo), it's for the education market but I've seen it available online. It's also a touch less expensive. Interestingly, there is an option to program it with Scratch (http://info.scratch.mit.edu/WeDo).

What you are talking about (a new OS based on BeOS) is Cobalt, which nobody wanted, not even Palm.
BeOS had some nice ideas, but if it was really that great they wouldn't have gone out of business.
Case in point: it was supposed to be so great with video, but personally, on a PIII 750, I found that mplayer on Linux performed a lot better than VideoLAN on BeOS. If the situation was reversed, I would have bought it. Alas.
