I just read a review of the Treo Bluetooth Headset on CNet

http://reviews.cnet.com/Palm_Treo_65...2.html?tag=top

I own one & find it very useful. There are two main problems, one highlighted by the review

Voice dialing is not properly implemented. This is a pain for handsfree dialing when driving, but it is an issue with the Treo, not the headset. Palm HAS to address this in a future firmware release across all models or it will be a reason why the unit will lose market share

The other is that I like to use it with VOIP on my Mac, the audio is fine but the headset button doesn't pick up/hang up calls due to the handsfree profile not being built into either OSX or Windows .

Bluetooth is a liberating technology. We just need to be able to use it properly on the cutting edge devices that are Treos & Macs.
