If we're talking about internet connectivity of such mobile device,
then Bluetooth isn't good idea. Where would you like to use BT as
internet connection? In home? Well, in home you can use PC to connect
with internet. Outside? You'll have to have your laptop with WiFi (or
something else) connection and bluetooth to share it with NanoNote.

I have Freerunner, and I didn't use bluetooth yet at all (except one
day experimenting with BlueMoko). My WiFi router has Bluetooth
connection option, but it's crappy, unstable, with little strength
signal and really slow comparing to WiFi. I would really like to have
WiFi module in Ya NanoNote. It's power-hungry? Why not just power it
off when it's unneeded? :)

I think WiFi and USB host are the most wanted features in future
NanoNotes. In my personal "i want to" list I have also 640x480 screen
and maybe touchscreen, but I understand having everything everyone
wants in device is impossible and very expensive ;)
