armb | PDA choice.

My Psion is dying. The obvious choices seem to be buy more Psions at increasingly short intervals off eBay as they die too, a factory reconditioned unit, or switch to a Palm, or maybe a PocketPC. I'm currently thinking a low end Zire would be adequate for what I use the Psion for (address list, calendar and to-do list, and occasional random notes of stuff).
Anyone have suggestions or recommendations?
