Just a few years ago our office (two floors, Fortune 500 company, more than 100 people on site) had a 100Mbps connection to the Internet (and a dedicated 1Gbps to a branch office). We had video conferences, mirrored OSS and back'ed up over the 'net. The dedicated link was at times a bottleneck, but I don't recall that the link to the Internet ever was.
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.
Honestly, I don't saturate my connection 99% of the time. I could have done that 10/15 years ago when I used to torrent a lot.
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.
