Once the Android platform starts offering a default security posture somewhere above "wide open barn door", that always provides the latest Android updates and doesn't involve installing a rootkit on your phone, I may give it some consideration.
Also don't somewhere around 80% of the available Android phones on the market have JTAG connectors on them? No thanks. Cool if you want something hackable, but not cool for a device that follows you everywhere and knows everything about you.
Edit: This seems to be an unpopular opinion, but really platform and application security are a feature set and it happens to be the one where iOS is kicking Android's ass. Some people may or may not care about it, just like some people may or may not care about battery replacement. For me it's the #2 thing I need my phone to do after make and receive calls.
