Android TV may sound like a semantic difference — after all, Google TV was based on Android — but it’s something very different. Android TV is no longer a crazy attempt to turn your TV into a bigger, more powerful smartphone. "Android TV is an entertainment interface, not a computing platform," writes Google. "It’s all about finding and enjoying content with the least amount of friction." It will be "cinematic, fun, fluid, and fast."
The thing about convergence was that people wanted the technologies in the background to converge, but they never wanted the experiences to converge. Watching video is ideally done on a TV; web surfing is ideally done on a tablet, and writing a novel is ideally done on a PC. That’s not to say that we shouldn't be able to do all three tasks on all three platforms, but we don’t want, e.g., the full PC experience on our TVs.
