Before you get excited by the prospect of using your HTC EVO as a remote control for YouTube, Google, and the web, I have to tell you that I haven't been able to get this working on my EVO (rooted, Froyo, SteelROM RevG). It works beautifully on other devices, though, and it's supposed to support Android, so my experience could just be unique to . . . well, me.
Now that that's out of the way, let's talk about TubeMote. Not to be confused with TubeMate (note the "a" there), TubeMote lets you use a remote browser (in this case, the browser on your phone) to control a custom channel created when you sign-up for a free TubeMote account accessed on your computer via FireFox, Internet Explorer, Chrome, Safari, or Opera. When you're signed in to your account on the remote browser, you choose where you want to go from the drop-down menu, use the search bar at the top, and then watch YouTube videos and surf the web on your computer.
It works best for watching YouTube because there's no way to use the "remote" to scroll web pages or click on links [Note: RemoteDroid might be able to work in conjunction with this]. The YouTube interface also has simple playback controls, video quality options, and volume settings.
Again, I wasn't able to get this working on my EVO (the browser—stock and Dolphin—crashes after I type a letter into the search bar), but if you can get it working on yours, it would be a sweet setup for watching YouTube on your browser-connected TV or a large monitor while you're kicking back on the couch. You could also share your custom channel URL with friends and control what they're seeing on their computers.
What's particularly nice about TubeMote (yes, that's an iPhone 4 shown above) is that it doesn't require an app or any kind of configuration to use. You just sign in on your mobile device, go to your channel URL on your computer, and start browsing.
The front page of the TubeMote page clearly indicates Android support (as shown below), so I don't know why it doesn't work on my EVO. It doesn't work on my Dell Streak either (rooted, Froyo), so maybe it has something to do with Android 2.2. I don't know.
In any case, it's cool if you can get it work.[TubeMote] Thanks, PHADE!
