Few of things I've noted since upgrading:

1. WiFi connect happens immediately upon bootup - is this the behavior of the N800?

2. Bluetooth keyboard connects, but never auto-connects. Always have to go through Control Panel/Bluetooth/Devices/Connect, etc. - anyway to get it to auto-connect like bt-plugin on N770?

3. Seems to constantly charge if booted (or indicate charging, even if disconnect from WiFi). If off, it will complete charging, and indicate same.

4. Application Manager seems to be AWFULLY slow, much slower than N770 Application Manager.

5. What I've done so far with Opera - it's much faster.
