I would personally prefer bluetooth before WiFi and other types of
radio, i would have so much more use for it. There might not be hot
spots the same way as for WiFi but it could let NanoNote communicate
with mice, keyboards, cellphones (Internet access everywhere),
laptops, desktops, PDAs, Lego and more. And compared to the other
radios (434/868/915MHz) discussed here, Bluetooth is already in a lot
of electronics out there. I already have it for most of my computers.

I don't know what it would cost to implement bluetooth but there is
really cheap and really small usb-bluetooth adapters out there.
