For last 7 years, I have always needed to use a Palm PDA and Cell phone for my work. When the Treo 600 came out last year or so, I decided to wait till they get the bugs out. The Treo 650 did come out 1/2 year ago for Cingular and Sprint...but being on VZW and didn't want to pay to get out of the contract, I waited for the VZW Treo 650 to come out.
I'm happy to say that it's been great to use. Now, I only carry the Treo 650 for the past week (transferred all the programs/data, etc. from my Tungsten) and it's great. Don't need to carry 2 things anymore.
The Bluetooth on the VZW Treo 650 pairs up with BMW BT/Assist module with no problems. It also paired up with my old Motorola HS810 BT headset.
The PDA is fast and has non-volitile RAM (so even if the battery dies, all the info stays). Unfortunately, the memory is limited (they should have had at least double the RAM). However, I do have a 1GB SD card and move some programs and data on the card.
The phone works great, speakerphone is great, reception is fine and love the integreation of the PDA with the phone. And you can check e-mail, SMS, and surf the web!
Last night, I was @ a dinner program and it was kewl getting on the "web" checking the NBA final game score. Also, you can still browse and post on X5world as well (I already did it the first day I got the Treo 2 weeks ago or so).
Anyhow, if there are any other Treo 600/650 owners, let me know what good programs are out there for it.
