I downloaded the demo of IntelliJ IDEA with the intention of playing with Android this morning. Setup was a lot more difficult than I expected, in that I had to do a lot of configuration before it would work, but it wouldn't outright error. So, creating a new project before adding the JDK and Android SDK resulted in an empty src and gen directory, but of course, no error. Once I fixed that up and opened an existing Eclipse project, it seemed OK, but not enough to wow me senseless. The GUI editor didn't seem to understand my layouts, so I was presented with the XML layout instead. This bummed me out since I wanted to see their GUI editor.

So far, not that impressed over Eclipse, but we'll see. I'm going to keep monkeying with it for the rest of the day.
