This may only appeal to, well, me, but this is one of the reasons I wanted to get an Android phone. I figured out how to take a screenshot of my phone via the SDK in Linux. The cool thing is that it also exposes a lot of the inner workings of my phone so I can see how everything is stored, running processes, etc. It's like a geek-o-rama. This is one thing that convinced me not to get an iPhone/iWhatever, because none of this stuff would be exposed, much less in Linux.
