Many thanks to Lew S. who commented on a previous entry of mine:
re: Palm TREO 700w â€¦ â€œJust a warning, this is a Windows Mobile Palm device, so if you already have a Palm, none of your software will work on this cellphoneâ€

He linked to this excellent article about a Palm OS emulator for your Windows Mobile machines like the Treo 700W.
Suddenly, Iâ€™m not so worried about Palm OS dying an untimely death. As long as my WWCalc program works, Iâ€™m happy.
