The Nokia 6670 is basically the 7610 with a decent keyboard:
Notes:
Bluetooth services as reported by Mac OS X: SDP Server, SyncML Client, Nokia OBEX PC Suite Services, OBEX Object Push, Dial-Up Networking, Hands-Free Audio Gateway, OBEX File Transfer
Pluses:
- Does not look like a goth bathroom tile.
- Firm but responsive cursor pad (much better than the 6630's).
- OMA-like presence and chat clients, integrated with address book (not tested, not sure if they are compliant).
- The usual decent Nokia megapixel camera.
- It's a Series 60, if that's your thing.
Minuses
- Ugly mirror outline around the display.
- Size (longer and wider than my V800, even if slimmer).
- Bottom row of keypad is too small for easy use.
- RAM is short for running Opera alongside anything else.
- Same Bluetooth shortcomings as other Series 60 devices.
