I follow activity monitors rather closely. The wifi connectivity is the most unusual part of this design.

There's never been a nice, simple way to setup wifi from a small device before.

The trick they are using here is to use the Bluetooth connection to setup the wifi. It's not a bad approach (in fact, they like it so much they're trying to patent it).

But TI recently came out with the CC3000, a wifi chip that can grab the setup information on its own (well, with the help of a smartphone app).

This avoids the hassles of managing two different 2.4GHz wireless systems on a small device.

I think that's where the future of wifi setup is heading.
