>If you develop on x86, then you're going to want to deploy on x86, because you'll be able to run what you test "at home" (and by "at home" I don't mean literally in your home, but in your work environment) ... This is true even if what you mostly do is something ostensibly cross-platform like just run perl scripts or whatever. Simply because you'll want to have as similar an environment as possible

Eh, Android's existence is a pretty big counterpoint to that. And you could just run an ARM VM on your desktop if it's that important to you.
