I believe much of the issue behind creating an Android app is that none of the Android tablets (and devices in general) have a standardised screen size, whereas iPads are all the same size, then iPhones and iPod Touches use the same screens.
I, too, would love an Android version, but I can see why it would take precious development hours to create a GUI that worked in multiple screen sizes.
Looks I’ll have to become a slave to ‘the man’ 😛
