I use a Palm Centro. I need it for work. Yes, I use outlook for my home email and calendar. I can't get the wireless sync to work with my calendar but it is fine for my email. I use the wired sync for the calendar. I have wireless sync for all of my work stuff-email, calendar, etc., but that is with a program from work.
I don't like my phone at all but it is the only choice I have. The Centro is a HUGE battery hog-I recharge it daily.
