I have a Tungsten E that is my current PDA. Now that I have my Treo 600, I would like to be able to Sync both of them on my computer without having any problems. Right now my T6 and T-E have different user names, and I can Sync both of them with the Palm Desktop that came with the T6. Problem is, I get a lot of error messages when I Sync either device. Also, it causes trouble when trying to install new programs to either one or use the same program on both of them. So what I'm really asking, is it possible to use both on the same computer without problems? And is there anyway to have information updated on either device or in Palm Desktop, to be Synced with both devices? thanks
