The main problems with Bluetooth, IMO have been the implementations, not the technology itself.

1. I don't think the technology was exploited or used as widely as it could have been given all the promised being bandied about before it was introduced.

2. Windows and WinCE and WinMo suck. Bluetooth on these systems is going to suck no matter who makes the device.

3. The Bluetooth problems I was alluding to when I first mentioned them were related to mouse usage. I've just not found that Bluetooth mice are as responsive as those using other (proprietary) wireless technologies. I've tried Logitech and MS BT mice on Mac OS and Windows (where, referring back to #1, I might expect it to suck).

4. BT keyboard usage on the Mac with Apple's BT keyboard has been great.
