I'm desperately trying to fight the urge to say the following: "I've got an Android emulator, it's called the Java VM... ho ho, he he!"
I thought there was already talk of some manner of compatibility layer for the Pandora, allowing it to run Android apps... I could be imaging things, though.
When all's said and done, there's no substitute to getting Android up and running natively on the Pandora, I look forward to such a time as I've yet to get myself an Android device for software tinkering/testing. Of course, I've got to get my Pandora first!
