Well, it just might be time to sell the Nexio. I would say the Nexio was ahead of its time, and had to have been a design influence on the Advantage X7501. You do trade off higher screen resolution, but gaining the unlocked GSM and HSDPA certainly is a big plus.
We certainly are covering Bluetooth headsets in our full review. Given that you can't talk directly to the device, headsets are pretty important . Our Advantage shipped with Cyberon's Voice dialing which works over BT headsets-- also a plus.
