The HS850 was really a noticeable improvement over the HS810. I get a better range (approx. 20-25 feet) than with the previous model (only 10-15 feet). I am using the Treo 650 and am extremely disappointed that Palm did not splurge for Bluetooth 1.2 with my phone.

My wife's Razor gets unprecedented range. I had always heard that the Razor got good range, but I got what I would estimate was 250 feet! While some may not believe that, it is true. And this was in an environment with several WiFi hot spots available. To put this in perspective, Bluetooth allowed me to get more range than my Linksys G router. I would attribute this to its frequency hopping capabilities. My wife would have been happy with 50 feet of range so she could walk around the house, now she can talk and take out the garbage (when I forget)!
