Since signing the deal with NBC it's really ruined my experience. I have had GC on my Roku for the last 2 years. No playoffs, No sharks / Kings (I am also in Sharklandia)
I really paid a big price this playoffs and watched the entire thing on my PC which was crap. I won't make the mistake again. If you love to watch HD clear picture and don't want to miss a game just get cable (and I really hate saying that)
If you are OK watching on your laptop then get center ice but expect to have to make tough decisions come playoff time.
