Hi Bads 1, so that's about 4.7 GB/month. That would be 1 DVD disk. If you calculate what a 56K modem can do, the theoretical max. if you run the modem all the time, is around 8 GB/month.
Broadband which is something like 100 times faster should do 800 GB/month or about 1 TB/month. Better, but still not good enough if you want to spend the evening watching Videos.
