had Comcast come out and install their Business Class Internet at my house on Monday. The left my residential service alone and ran new coax to the house. I cancelled my residential service as soon as they were done though.
Advertised speed is 12Mbps down and 2Mbps up. Speed tests are showing a consistent burst to 50Mbps leveling off at 13MBps down, and a steady 6Mbps up.

The best part is the low latency. I tried some online gaming last night, my ping never got higher than 20ms.

I can ping my servers at work and get less than 50ms responses. It's good enough to be able to run Outlook in online mode and never see a disconnect message. That's pretty sweet considering it is being done over a VPN connection where I'm in IL and my servers are in OH.
I should mention those response times were also while I was streaming music via Pandora, my kids were streaming Netflix to a TV in their playroom, and my wife was streaming HD content from Netflix to the main TV in the living room.
Ok Nerdgasm over.
