That's what you get when you let your politicians sell you out to monopolists.
With the shift to cloud computing, at least in the awkward hybrid phase, that won't suffice for a business of that size, but it really isn't obvious what a single person would _need_ a gigabit connection for. Perhaps you can elaborate.
The download part is great because now it's faster to buy a game on steam for instance and download it than getting in the car, driving to the closest store to purchase a physical copy and bring it home.
Regarding the upload, I built a small utility that stores the videos from the cameras I have at home to the cloud in a rolling window (I didn't want to pay the service from the cameras provider). So at any time I am uploading something like 7 1080p streams (it's more bursty as I chunk the streams every 10 minutes and upload the resulting files). So, while 1Gb is still an overkill, once you have the bandwidth you find uses for it.
