If you want to find out if that console is fun to use? Yes.

Probably the 10k would be a bigger showstopper for people that are 'just curious' to even give it a try, but in this case this guy seems like someone interested in a sneak preview.

The devkit buyer hopefully plans to build stuff, _generate_ money with it. It should be an instrument to generate income, the money is spent on 'tools'.

Glass? That's a gadget. I said it elsewhere on the thread: I do like the comparison with a developer kit, but .. most people that seem to get one/use one (even the ones mentioned in the very article) look like end users, trying to get a sneak preview. Not 'I want to build my business on Glass apps' type of guys.
