I bought one less than a month ago; to make a not-so-long-story shorter, I returned it after 10 days, after having used it only for exactly 1 week.
The reason? When I realized it doesn't sync Outlook notes it was bye-bye. I really wanted to like it, I was away from home for a few days and decided to only bring the Nokia but after the 3rd day I was sorely missing my Treo 650.
Pros: very stable; multitasking (hey, I use a Treo
); comes with some very nice apps; nice screen
Cons: not a fully functional series 40 phone in when closed; no vibration; the joystick (should really be called "pain-in-the-***-stick"); bad use of the screen
