I used to have a ton of issues with Comcast's Internet service. But over the past few months, they've slowly started to make improvements to the service. Specifically, they've really bumped up their upload speeds. I'm watching The Players Championship via my Slingbox and I'm averaging between 1000 to 1500 Kbps. This time last year, I would have topped out around 500 Kbps. Supposedly, they might be bumping up upload speeds for the standard service to about 4MB later this year. Can't wait!
