I'm not convinced the demand is not there for a large base unit to coexist with a baby brother handheld. Most of those 30years old and under think smaller is better, while most of those 40 years old and older think bigger is better. And I mean across the board: cars, guns, sex, and base station radios (please no off-topic posts from old guys who love their small cars and young guys who see themselves as studs).
I'm sure the 2010 census will show there are more over the age of 40 than under the age of 30, so I think the demand is there.
