The Treo 650 is pretty sweet. The pros are .. it's probably the best put together collection of features in one place. The cons are .. it crashes like windows 95.
I really want to start writing little programs for it. One that I want to write will enable me to use an LDAP directory as an address book. Add an entry, it adds to LDAP, list entries, it lists from LDAP, etc. I think it'd be really cool to have a centralized address book and information repository.
I'm still poking around at what the best mail client, sync software, etc is. I'm looking at missing sync, and SnapperMail. Both seem to be really cool and useful. I'm just wanting to make sure i dont waste money buying them. I could easily waste hundreds of dollars buying useless palm applications.
