It may be time to change

Ever since I've had access to computers, I've had a calendar and address book on one, including big main frames in the old days (OK, not when my only access was punch cards, but after that). As I've switched computers, I've converted the data to each new machine, and it looks like it may be time to do it again. I've had my calendar/address book on a Palm product for a while (after the EO and Newton became unsupported), but it's looking like the old Palm OS is yet another unsupported system. I'm considering switching to an iPod Touch, but haven't made that decision yet. I have converted the calendar data to an XML format (which is easily converted to ical via an XSLT translation). I guess I'll have to do something similar for the address book data.

One thing I've learned over the years: don't get too invested in any one file format, because you're likely to have to change in the future.
