GPS on Treo - Convergence

Earlier this summer I did a lot of research and shopping for a standalone GPS unit. A lot of what I learned appeared here at BrothersOnTech. My GPS shopping started because I switched to a Treo 700p. Prior to that, I was running TomTom Navigator 6 software on my Treo 700w. It worked great and allowed me to have a phone, PDA, and GPS unit in one device that I always carried. Of course, for GPS functionality I needed a bluetooth GPS receiver too, but I could just keep that in the glove box of my car. No big deal, and very convenient. However, the 700p could not handle running TomTom well. It ran slowly and did not allow me to use a bluetooth headset and the GPS receiver simultaneously. This led me to start shopping for a separate GPS unit. I finally settled on a TomTom ONE XL. After using it some, I discovered that I really missed the convenience of using my Treo. I didn't feel comfortable leaving the ONE XL in my car because of possible theft and also because of the temperature extremes in the car. I was afraid this could damage the unit. Because of this, I had one more device to manage and to remember to bring along when I might use it. So after considering this some I decided the best thing for me was to move back to a Windows Mobile based Treo, the 700wx. It has more memory than my 700w did which will allow for better multitasking with TomTom. It can also handle simultaneous bluetooth connections without a problem. Sure, using TomTom one the Treo means I'll have to sacrifice the large screen of the ONE XL; however this is more than worth it for convenience. I don't use GPS terribly often anyway. Not to mention I don't have the extra cost of a separate GPS system when I already owned the software.
