When WakeMate is finally released, I'd be interested in reading a retrospective by the founders on what they learned, and on what checks/changes to their development approach they have made for version 2. As they are discovering, development with a physical, hardware component can be very different from pure internet startup development. Hopefully any other YC startups with a hardware component are taking note.

I'd still like to buy a WakeMate, once it's proven itself, but I'm rather glad I didn't pre-order.
