I am considering buying a USB bluetooth adapter for my PC. Plan to use
it with my Axim PDA and Cingular cell. I have been to a number of web
sites but can only find one (Kensington 33348) adapter that is USB 2 and
bluetooth 2. Since USB 2 has been out for a while, I am curious . . .
why is Kensington the only manufacturer with a USB 2 adapter?
DO I need USB 2 and bluetooth 2 or are older versions OK?
Any recommendations or suggestions?

According to this:

http://en.wikipedia.org/wiki/Bluetooth

the Bluetooth 2 standard revision adds a data rate of 2.1
megabits per second. That should easily be handled by USB 1.1,
which can handle up to 12 megabits per second. While having
USB2 is fun, it doesn't appear to be essential to getting
the performance from the device.

If I read that correctly, bluetooth 2 is better than bluetooth 1, but
USB 2 makes no difference. What is the range of bt 2? Looks lie some
are 30' but some can go up to 100'.

In the Wikipedia article, it shows three classes for devices. When
you are shopping for a device, it will say how many feet or meters
of range it has. The actual distance will depend on both devices
on either end of the link. So, if your laptop has a 10 meter
Bluetooth device, and the remote Bluetooth peripheral has a
10 meter range, then you'll get the 10 meters. Or something like
that.
