Caps are things you have to live with because of the explosion in internet capable devices. My TV, XBox, Apple TV, sundry iOS and Android tablets and phones and collection of Macs and Amigas all share one ADSL line. Even though there's only three of us in the house there can be six or eight devices using the ADSL. We've hit our cap once or twice and the whole thing just slows down to dialup for the rest of the month. VERY annoying, but it's better than in the past where a bill that looks more like a mortgage statement appears in the post....
We have a 250/250 HGB cap, 250,GB peak, 250 GB off peak....
Just read this and had to reply a little OT but I'd kill for a 250GB cap. Try living in NZ for awhile. LOL :-)
