As usual I will be brief - but here are TWO great reasons to a avoid at all costs signing up for capped internet connections…
When I say capped, I mean signing up with a provider that says you can use only X amounts of bandwidth a month.
Reason #1: Monitoring your bandwidth usage is a pain if you alone use your PC/Mac…

• let alone if you have other users in the household…
• let alone if you have a kid surfing the net and playing games…
• let alone if your kid is hitting puberty.
• And BTW - please do put a security code on you wireless router if you use one. Apart from being a HUGE security risk, you dont want to provide free internet to all your freeloading neighbors, dont you?

Reaon #2: Certain programs use way more bandwidth that you would ever expect… especially if you are a gamer and play any sort of online game and especially MMORPGs.

• See this article at BBC News on the cost of World of Warcraft.
• See this article on Massively regarding the hidden costs of MMOGs.
• For those with more know-how, see this PDF file from the Vienna University of Tech regarding a Traffic Analysis on World of Warcraft.
