I am using the developer version of Android on a Chromebook. I've been using Aquamail and it works well. The one issue I've found is that since a Chromebook has a physical keyboard you find yourself really wanting to use the keyboard for various commands when using Aquamail. I know that this isn't the mode of operation on a phone and so not a current issue, but since Chromebooks sold more units than Macs last year, once the Android capability is released I think they'll be demand for lots of Android apps to support keyboard commands. Hope you'll think about it as a future priority.
