Its funny you say the answer is "Search" but of the 4 things you want to do when you fire up your tv, none of them are "Do a text based search for content".
1. Go to specific channel
2. Find if a program is playing right now
3. Browse a category of programs
4. Access an existing digital library.
Existing remotes actually do many of these pretty well. A keyboard based search only really helps with 2 and 4 and even then might actually be an ancillary experience unless you are looking for something specific. Text search only helps when you are looking for specific content it helps you find content you know exists. But I really don't think thats the main problem for people watching TV.
I think most people do what I do when I get home, sit down and try to find something interesting and new to watch. I think the problem is that most people have a hard time finding that cool new show or video. Now similar to the web, when I want to try to find something interesting I don't go to Google. I go to reddit or HN or fark or digg or some other source of curated content.
No, existing remotes do this horribly. Modern Cable subscriptions come with 300+ channels. I don't want to have to hold down an arrow key for minutes looking for something. I don't want to have to memorize what damn channel is AMC HD.
GoogleTV lets me type-in three letters: AMC. I get the channel. I get YouTube videos for snippets from their latest shows. I can type in House and immediately see if it's playing on any of the two dozen channels it's syndicated on, grab some episodes from my network, watch videos online of it, and read the Wikipedia page.
Try using a computer without being able to type actual words. You're only allowed to use the on-screen keyboard provided by your OS and the arrow keys to move around and confirm keys to press. I'll check back in when you're pulling your hair out trying to do anything in 5 minutes. The common computer experiences are merging with your TV. Apple's remote doesn't do anything to solve it. It's simple for the sake of being simple, and it's worthless as a modern computing remote because of it.
I've already conceded that if you know what you're looking for (A&E, House) a keyboard helps. I just don't think that's the primary issue which people have with their TV. 99% of the time I don't need Google on TV - I want reddit and I never use my keyboard on Reddit.
But you use a mouse on Reddit to select which story from a list to read, comment to expand, upvote etc which the Google remote has, and the Apple remote doesn't.
