Hmmm...
Quad core 900mhz, 1gb ram, same video core, compatible with RPi 1 and part of the RPi ecosystem; Well I think I need to buy a few, the extra oomph will help me build a nice new low power lab that can run 24/7 and not have to worry too much about the electric bill.
Windows, don't see the need myself, but also I don't see it harming anything, just more choice for the RPi community.
