I also use the i705. I just wish there was a network for it outside the US (e.g. Asia). I tried the PalmPak Travel Card: Asia Pacific Cities, which comes with additional software such as Time Travel, Time Book, Time Place and CurCalc. However, I find that the info is overly condensed, the maps are worthless, and overall it adds little value to my exising knowledge of cities such as Bangkok, Hong Kong, Singapore and Tokyo.
My favorite alltime time/clock program is City Time, with Cesium running a close second. Years ago, I threw away the built-in datebook, and replaced it with Datebk. I'm now up to Datebk4.
I spend a lot of time in Bangkok and nearby provinces, and thus have several map, BTS, business programs specific for that area. Included in that mix is the best up-to-date (a real challenge in that area) restaurant guide I have ever found to greater Bangkok. Most programs are advertised in Thai websites, but for some reason I ran across a number in the major Thai papers such as Thai Rath and Daily News. However, all these Palm programs are in Thai, and thus are of limited interest, I suspect.
I use TealLock 4.1 to encrypt and protect data, including mundane stuff like CC numbers, FF program info, etc.
Favorite games? Bejeweled and Traffic (waiting for more levels for the latter).
