Toshiba and Vizio are jumping into Google TV. That's good news. Samsung, also, and I understand LG are heavily considering it.
I predict that most people will have Google TV within 5 years. Damn near everyone I know has either a Samsung, Sony Bravia or Vizio TV. That's aside from all the Blu Ray players that will also include it, and Blu Ray players haven't yet reached mass traction either, so if there's a bunch of players that also include Google TV..... then that is a major win.
