I don't choose which data communications access I want, I choose which device I want.

Honestly, I couldn't care less which carrier I have (as long as I don't get ripped off either price wise or connection wise; both cases seem to not be rare nowdays though).

Let's say you're going to buy a console (which might not be the best comparison here). Then, do you rather want to choose the only non-prefered model that happens to be availible in a store near you, or do you simply get the machine of your choise somewhere else?
