To Sudenlink's Defense I use Suddenlink at home, and have switched a number of my clients from the antiquated DSL around here to Suddenlink Data/Phone. Most of them have been pleased.
I had all kinds of issues, but they were ironed out (finally) and have no major complaints other than the latency caused by ALL of their traffic being piped to Texas regardless of where you're from. (i'm 1000 miles away) Kinda sucks when your left 4 dead ping is NEVER less than 200ms.
I currently purchase their 12m/768k tier for $59.99/mo. The "business class" of the same speed (1.5m upload) is $500/mo. There is no freaking way you could afford to switch to the business tier.
It seems that we have used just above 66gb total for the past month. It's just my wife and I in the house. I torrent a TV show or two from time to time, play a FEW games, work on customers PCs at the house from time to time downloading updates etc. What i'm sure is the major bandwidth consumer in my house is that we have Vista Media Center PCs in the living room and bedroom, and instead of cable we use the Netflix Media Center add-in, and now the Hulu Desktop Media Center. I'd say we're average bandwidth consumers, considering I don't know anyone under 30 that watches traditional cable anymore.
