Just a few highlights so far.

My old WoW latency was around 80ms(Home) and 100ms(World)... MS = the number of milliseconds it takes for the server and my computer to communicate.

THIS is what it is now: http://i.imgur.com/G4taW73.png and that's during peak, with youtube running on my iPad, and with my mother watching Netflix downstairs.

Also, I deleted and re-downloaded Sonic Generations to test Steam's speed with the new service. In under half an hour I've downloaded 2.3GB out of 7.8GB. With TWC this would have most likely taken all night.
