Wow...so ATT is going to let me pay to make their crappy service better? Gee, thanks.
I don't think this service is intended for 99% of of the population. I think this service is intended for the 1% of the population that live in such remote areas that they do not have a cell phone tower anywhere near them, and for people that live (or work) in basements of buildings and in urban locations where the geography of buildings is blocking them from cell phone reception. Yes, all of these people could use a land line, but maybe they want to use their cell phone (for obvious reasons; contacts, caller id, lists missed calls, voice mail, texting, etc, and it's all on the device they can walk out the door and go somewhere with).
