This is sorta old news, but new to me:
I've heard about Joost since it was called "The Venice Project". But I've never installed it before now – it required an Intel Mac, and I had a G4 Powerbook.
Well, yesterday I recalled wanting to try Joost, and realized that my recently-procured MBP should run it just fine. Five minutes later I had it installed, running, and...
Woo hoo! They have Adult Swim! :) It's FAST and the UI makes sense. It really feels like a "TV 2.0" experience.
If you need a fix of Sealab 2021 or Aqua Teen Hunger Force, I recommend you install Joost, stat!
