The incumbents love to ridicule Gig connections. AT&T sneered at the whole concept until Google announced they were going to do Gig fiber in Austin. About eight minutes later AT&T announced they had found a sudden need for Gig service in the Austin area (but nowhere else in the country...apparently Austin is "special" in AT&T's mind).
A colleague just sent me a screen shot that illuminates perfectly why a Gig of bandwidth might be occasionally useful. He had a hard drive crash, and being a smart guy, had everything backed up to offsite storage. The screen shot showed the time remaining to restore about 10% of his total file structure: one and a half days. If we multiply that by ten and assume that everything runs perfectly throughout the restore cycle (in my experience, a big IF), we are looking at about two weeks just to get your files back. Yea....AT&T is right...who needs a Gig?
