The notes still do not sync OTA. You can do it via tethering, but I refuse to use Craptivesync on the computer. WM6 is MUCH better IMHO than 5. You won't see a lot of changes to the UI, but it defintiely will give you some added stability, speeds that are at least 2 times as fast (thanks to HSDPA) and overall more robust. Example, Office Mobile 6.1 comes included that gives you access to view and edit docx, xlsx and pptx files that are created in Office 2007. Overall, worth the pain of having to wipe the device and start over. I'm definitely happy, and that is hard to do with me!
