I DON’T BELIEVE IT!
The new set-up for my Palm T|X has wiped my entire appointments calendar, for some reason.
Luckily I still have the old one at home and can backup from that, missing only changes made in the last week. But it is DEEPLY aggravating.
[Edited to add: Even more luckily, there was a backup at work, so all is now restored. But
I did say that HTC battery life was down to the exchangeable batteries. Perhaps I should have made this clearer. (I have a particular use case in mind here: another cyclist in my club can record a GPS track of a whole day’s ride on his HTC Desire, by exchanging batteries halfway, whereas my iPhone gives up after about 4 hours.)
