Comcast Considering 250GB Cap, Overage Fees → What?!! Why the cap now?!

Well, I'm not a big downloader but I hope it don't affect me.
I usually use it to watch movie and play online games (I sometime leave it on for hours).

I just hope playing online game wouldn't waste that 250GB in less then a week. If it does, then I'm going to consider going to ATT DSL. LMAO.

You'll be within those limits for sure. Some estimated values so you get an idea:

WoW 5-15mb per hour
Call of Duty 4 15-20mb per hour
Crysis 20-30mb per hour

Even if you played Crysis on a busy server 24/7 for a whole month you'd still only have ~22GB of traffic.
