Maybe....
I have really no issues with the 6700 but I had a 650 and like the form factor (I could use my 650 case and 2400 battery too).
Plus, it has WM5 AKU 2.5 on it (we have 2.1) and I want to see what's changed...
(<--that's hardcore nerd)
If it has built in pic-mail and threaded SMS like it reportedly does that's kinda cool.
But damn is it expensive! We'll see.
