I own Glass. 99.9% of people who see me wearing them want to know more about them. They want to try them on and experience glass. And of course, I let them give Glass a whirl. They love it. Yes it's WAY too pricey but, it's still awesome. I don't find them that unattractive. I look at it like, "I'm at a sporting/concert event and I obviously want to take pictures, so I'm wearing this, which is more convenient." Once I explain that to people, they totally get why I'm wearing Glass.
Glass makes sense and it's a step in the right direction for wearable computing. At least for now.
My gripes:
It needs Bluetooth LE. I'm an iOS developer. I need Bluetooth LE to support notifications at least.
iOS is hamstrung until I can send iMessages. I don't see that changing.
Swiping through all the cards can be kind of a nuisance.
Battery life.
Google is a software company so, I imagine the more Apple opens up their notifications etc, the better Glass will get.
