I use Clear in the Dallas Area. The USB dongle runs 3 to 5 mbit at work (24 miles from home) and the ‘Box’ runs 2 to 4 mbit at home. As with any RF system range is going to be an issue, so is its inherent bandwidth limitation (as with any system). Yes sometimes the data rate can get real bad, even drop out. This does not usually last a long time but it can be annoying. I have never experienced anything that I would believe as targeted or intentional limiting, however if enough people suck on the same straw at the same time what do you think is going to happen? As far as being able to get out of a contract for poor performance, maybe that has merit I don’t know.
Clear (sprint is involved here) has been having financial challenges lately, personally for me it would be sad to see them go. By the standards of the cable companies I would be a download hog. (multi part large WinRared binaries ..Clear provides me an alternative option, I Live in an urban connectivity hell, DSL for me is at best 2mbit, usually 1.4 or so. There is no upgrade available yet ( 3 blocks away it is a different story), and no Fios in my neighborhood. I own my home and it is not something I would sell over something that in 5 to 10 years will change.
