As a Comcast customer, I was happy to read that it's planning to roll out 160 Mbps Internet service in 2008. I'm not expecting much, however. I currently pay extra to Comcast to get 8 Mbps service...and I routinely get closer to 1 Mbps and 2 Mbps, tops.
So while Comcast can talk up 160 Mbps, I won't hold my breath. At its current ratio of promise to delivery, however, I'd still be at 20 Mbps. I'll take that.
