Despite the problems Google had initially shipping physical products over Play/Wallet, I suspect this will be more polished. The showroom they have for the Google Fiberhood appeared well run when I encountered it.

Google is moving from the "web" to the real world, and closer to customers and also making hardware themselves. The next 5 years should get very interesting for them. They need to build these stores fast, though. Adding 5 stores per year won't change much.
