I've been using a Palm IIIc and a Palm IIIxe interchangeably for the past few years to read e-books, downloaded news articles, write short stories, notes, etc.
I use the Palm IIIxe when I know I'll be reading outdoors where there's a lot of sunlight. For indoor use, I stick with my Palm IIIc.
Haven't really felt a strong urge to upgrade, otherwise. Don't need a digital camera, MP3 player, hibachi bbq, toe massage, whatever. I just need the ability to read plain ol' ASCII text and somewhere to store numbers and addresses.
