Quite a few of these winners, particularly the ones who are 'normal' that Google wanted to have as non-tech nerds, aren't actually going to fork over the $1000 for the glasses though. A friend of mine, a normal college girl, won 'the right to purchase a pair of Google Glasses', but says that she probably won't buy them since she can't justify the cost.
The ones who are most likely to fork over the $1000 are the tech nerds who place comparatively greater value on having early access to such gadgets. Google is probably going to see a strong skew towards tech nerds greater than the initial distribution of contest winner backgrounds.
I wonder what's going to happen with the left over Glasses.
