I have and love a Palm Treo 650 (link updated). It is fairly old now (about 100 years old in gadget time) but still working well. Bern was using on the weekend and was bugged by an idiosyncrasy I’d never been able to work out. received SMS messages were dated into the future, often the next day. After a bit of playing, we worked out they all seemed to be 18 hours and 10 minutes in the future which is a fairly odd number.
