Is it viable?

Something that's been on my mind for a while now. Is it even viable to use a Palm OS device on a regular basis? Could I manage? Could I do all the things I sort of take for granted now? I'm not sure. It's a maybe at best.

The reason for asking is because I'm curious as to whether or not I could get by just with an old school PDA, or more likely smartphone. I'm thinking of something like the late Palm Treos. Maybe a 680 or even a Windows Mobile device.

It's something I'm going to give more thought to over the coming days and weeks and see where it goes.
