I agree. The barrier to entry for developing iOS apps is too high for me, as I'd have to buy a Mac and, realistically speaking, an iOS device for testing. But I can run the Android SDK on all my computers, Windows & Linux alike, so development is available wherever I am.

Also, the Android SDK works really well for testing with a physical device. Plug in by USB, or use wireless ADB, and it only takes a couple of seconds to deploy a debug package to your testing device. Much faster than using the emulator.
