We never reached 1TB in a month. 6 people in a household and at least one person streaming something in HD at some point. Also uploading HD media projects and audio projects for schooling.
UBB deters people from using more competitive services like Netflix, HBO GO, iTunes, CinemaNow, etc. It competes directly with their core business of television. Seems very anti-competetitive. Cogeco does not offer a reasonable plan that would allow for such services to be used as your primary source for movies, TV and music.
