fwiw you CAN (and I do) script on android in languages other than Java using Scripting Layer for Android (SL4A). And you don't need to be on a separate machine to do it. I made a little Perl script the other day on the train 'typing' away with my thumbs
Here's the google code site: http://code.google.com/p/android-scripting/
I think to discount Android for the Pi because you can't program on it makes no sense. Perhaps it would be more accurate to say you have other more important priorities... like getting them out the door.
