My opinion: Google is selling and pricing hardware based on software capabilities. For a lot of people, myself included, some of these features are amazing. That said, at the end of the day, it's still a $160 version of something that are commonly broken, and have cheaper 'dumb' versions of for a few bucks. This makes me really hesitant to buy.
Ideally, what I'd like to see to make myself, and I'm sure some others, a buyer is a free replacement program. I'm more than willing to support awesome software if I don't have to worry about it's backing hardware breaking so easily, especially something a lot of folks jam in their pockets.
