At what cost though? My guess is that they have features planned out far in the future for their iOS apps, what should they give up there in order to port something to Android?

The same argument has been made for years for Mac specific apps. I for one am pretty glad that Panic has not taken the time to port any of their apps to windows, it has let them continue to make some of the best software in the world. None of their attention has been diverted to porting what they have already done.
