I have had my 7135 for about 14 months now, and while I enjoy using it, I find myself longing for the integration (palm and phone) and stability of the 6035. I actually still use my 6035 for going camping or anytime which I could damage my 7135. (You can change ESN's on Verizon's web site whenever you want under your phone account.) My question is for the people that have had the 7135 but switched to the Treo 600. I don't think that I want to change phones until there is an integrated bluetooth radio option, which the Treo doesn’t have, but I am curious to how the Treo compares to the 7135 in stability, physical build, and integration of the phone and palm side. I refuse to switch to any Microsoft product out there. Thanks in advance for your time!
