The hype around this thing is spreading across the net, even Robert Scoble is talking about it.
But what's it really do? OK sure it's a very fancy piece of technology, and the idea itself has potential. But seriously if you want to spend $400 and get into learning about the sky. Buy yourself three things:
Decent pair of binoculars, with at least a 50mm aperture.
A solid tripod, won't see much without one.
A astronomy book, with charts etc in.
You'll get far more enjoyment out of that then you will a fancy talking box. If they bolted the technology onto an instrument, so you can actually see something, then sure it would be great. But not being able to actually look at anything, what's the point?
speaking of binoculars, my friend was just talking with me about them today. He was telling me about the IS feature. I thought it was pretty spiffy. Looked 'em up and damn, the IS feature costs a lot. Wonder how it works
