If it's like the 1050, one big factor will be sound quality - not something that shows up on a feature "laundry list," unfortunately, but one that matters nonetheless and one that kept the 1050 popular for a number of years. Another factor will be customer support and service. Will there be any others? We won't know until we see a final feature list. Even then, we won't really know what the real "key benefits" are until we start hearing from people who actually have 1070's in place and running.
