How is it overpriced when its the same price as most other High end smartphones. Its not meant to sell well either, Its for those who want a developer phone that's uber high end. I would never get one seeing as you can get a Nexus 4 and 7 for that price.
Still we got a ton of announcements and unlike other companies google usually has feature updates separate too OS ones. Plus this was way more dev focused than past i/o's
