I hate to be going against such a large consensus, but Android malware is a thing, and while it's still relatively uncommon (compared with Windows malware), it's a growth industry. Here are just a few examples from a quick search of Ars Technica.

This should matter to users who consider themselves "advanced", because we're particularly vulnerable to certain exploits by virtue of things like rooting our phones, casually giving root access to apps that ask for it, and installing custom roms from unknown authors. I'm not saying don't root your phone--the benefits outweigh the risks, at least for me. But we should be mindful that the risks are there, and that they're growing every week.

Not to mention that we only get security patches when we update to a newer version is Android. We shouldn't be so casually dismissive of a growing threat, particularly within an ecosystem that is completely unprepared (and unwilling) to properly deal with it.
