I'm looking to buy this tv. I like using a ROKU if possible. I'm not sure this TV works with ROKU because the following phrase is used on the description on Amazon: "GOOGLE TV: Google TV organizes movies, shows, live TV, and more from your apps and subscriptions, offering personalized recommendations based on your interests." I looked at Hinsense site and couldn't tell if I can use ROKU instead of Google.
The built-in User Interface, Google TV can't be replaced. But you can buy Roku and plug into Hdmi input on your new tv. You might be able to have the tv turn on to the hdmi input the Roku is connected to, bypassing the Google TV UI altogether? Roku tvs can.
I just bought the Roku Pro 65", and extremely happy.
