I had one of these for a while (actually the RM-2000) and it is a very neat toy, but a really crappy remote. To use it properly, you really have to hold it with two hands. Its learning features were disappointing. The button layout kind of sucks. I'd really recommend going with something else. It is a nice idea, and it'll impress all your friends - but the fact that you have to look at it, read the buttons, tap the buttons, scroll through menus, etc, makes it difficult to use.
The good news is that it'll control about anything. But from a usability standpoint, you are much better off with a remote that has buttons you can feel, that fits in one hand, that you don't have to look at to perform common operations. The sony only has two commands that are not part of the LCD - channel up/down and volume up/down. And then even these aren't easily distinguishable, the buttons are identical and not backlit.
So - what you see is what you get. Take a good hard look at it and make sure you'd want to try to fumble with it in the dark...
