Hopefully somebody could tell me how much does 6GB(per month) usually equate to.I don`t do downloads music etc but I do browse the net for at least 8 hours per day.
If you do not download films, videos, or music then I doubt if you will reach 6Gb a month.
Everything you look at on the web IS downloaded to your PC, but all the words are just plain text documents (HTML files) and most of the pictures are small GIF or JPEG files.
So if that is all you do then you are probably OK.
