I'm actually a big believer in Glass. In my mind getting the average person to use them is actually simpler than it was to get them to use a cell phone. Everybody has sunglasses and they're used to wearing them (even indoors). With phones it was a complete new paradigm. People weren't used to carrying a phone with them and most didn't feel they needed to, and we saw how that went. As for pricing and design, 6 years ago phones were expensive bricks and look how far they've come. I feel the same about wearable computing and glasses especially.
