ZBoater: Thanks again for your help. Here are some responses to your questions/points: 1. Once buy and start using a Treo 650, I will stop using my T|C. 2. I have checkpoints stretching back over about two months the reasons you mention (I've been well trained by you experts). 3. I will start from scratch. I wanted to prove to myself that I could get the T|C RAM size down to a level that would work fine with a Treo 650. I expect that after I freshly install all the apps that were also in my T|C RAM and use the T650 for awhile, that the RAM size would be similar to that of the T|C. 4. I do use ZLauncher and like it. Just for kicks, here's a list of most of my third-party apps: xABFR xAdobe Reader for Palm OS 4/14/05 AvantGo channels AvantGo.prc 2/10/05 Avantgo-AG Connect BackupBuddyVSF 3.1 7/14/05-Archive Bible ToGo Card Export II 2/13/05 Cleanup 3.27b 2/15/05 Crashpro 22 4/18/05 DataViewer DateBk5 5.4a 4/3/05 xDateBkCat Docs to Go 7/14/05 eReader 2.61 4/17/05 FileZ 6.6 4/19/05 IconMgr/Icons xJavaHQ (Pocket Poems) Maltin Movie Guide xManageXT Mobipocket xNet Chaser 1.51 2/21/05 xPocket Poems PrintMe xSmall Talk SnapCalc SplashPhoto 1/29/05 TrackerDog 2.11 2/17/05 Uninstall 2.62 2/15/05 xUnited 4.0 5/30/05 Vindigo WorldMatePro 2.0 2/29/05 Zagat Zlauncher 5.20 4/3/05 In all cases, I only have the minimum amount of each program on the RAM that would still allow the app to open at acceptable speed (IE, not 10+ seconds). Where possible, I've moved as many of the apps associsted with a particular program and mostly all the associated databases to my card. In a few cases, the entire app is on the card. I have 16M in RAM and 103M on my 1GB card. Using the source that I sent to you earlier, I found that pretty much all of these were reported to work on the Treo 650 except for the ones marked with an "x" above. In fact, those were not either on the working or not-working list. They were simply untested or unreported. I can email the their creators if I really need them. So, it looks to me that clean installs of most of these should work. I'll save the "x" marked apps until last. I would image that Adobe and United would not be problems. Any other comments? I don't like redos so I tend to ask for a lot of advice from a range of "people who know" and am very careful. I very much like your point about regular backups after each couple of installs, a procedure that I followed a few months ago when I changed PC's. Thanks very much for your help and patience.
