This could be what pushes me to start Android development. I just traded one of my spare iPhone 4s for a Galaxy Nexus, and started to dig into dev. But from my admittedly brief foray, it looked like a lot more fiddling than I cared to undertake right now. Sure, I use a combination of vim, xcodebuild, and a small bit of Xcode now, but if Xcode didn't exist as an IDE when I started iOS/Mac dev I wonder how far I would've gotten. As soon as the download link for the Android IDE is published, I'll be taking a concerted look into it.
