Finally there's Google TV, the system built into the Logitech Revue product, which recently saw a price drop from $249 to a much more user-friendly $99. You get a full-featured Web browser with an actual computer-style keyboard, complete with touchpad for mousing around. Some people complain about using a keyboard to control their TV, and there are more compact alternatives; a smaller remote control as an optional accessory, and downloadable remote control software for smartphones and tablets. But for browsing and searching, you really can't beat the convenience of a keyboard that's actually built for typing.
Here again, there are preset apps available, though the selection is fairly limited right now. Where this gets interesting, though, is a software upgrade promised by the end of the summer that adds an Android Market service, similar to the one found on Android phones, for downloading new apps to the system. Frankly, it's too early to know whether software developers will jump on board and unleash a flood of apps for your Google-fied HDTV. Even if they don't, though, you still have the most practical solution for enjoying browser-based entertainment on your big-screen TV, at a reasonable price.
