Some details: With bluetooth you can get 4-5kb/sec. Really not suitable for lan and Co. But for ppl using dialups it should be just fine. As for the range:
I can use my handy in a zone of more than 20m INSIDE of the building. Using an msi bt2usb and SE t610. I wouldn'T really call it short range. It's perfect for peripheries.
Eventhough there are bt printers, I think this is almost the worst concept. Transfering print-data is pretty heavy and too much for bt. Anyone ever tried this?
