I have been a Palm Treo user for many, many years. Starting with the Treo 600 and last week giving up on the Treo 755. Well I'm beginning to learn more and more about my droid everyday. If I run into any problems I gather that this is the place to ask. Here is my first of many. How do I "dismount" my unit from my PC. I know that I have to mount it every single time (nuisance). But how do I dismount? TIA.
