hmm that new palm zire 31 is looking pretty attractive. however, i'm pretty sold on the address book and calender apps of Mac os X. i would seriously think about getting one of those palm things if i didn't have to switch scheduling and contacts programs on my computer, but i have a feeling they make it a pain to use anything other than their own software. but palm has been around for a while, there should be some experience with this. does anyone use a palm PDA with their Mac? can it be jury-rigged so that calender and address book can be synced up with the palm PDA and vise versa?
