There is rumbling that indeed Android is to iOS as Windows is to OS X. That is a mostly fair analogy, Android is more open and thus slightly more dangerous (and so forth); you could spin out the idea as far as you want to.
But then there are those Android fanboys who hack and tinker with their phone so much that in the end they accidentally have a Hello Kitty inspired background that they just cant uninstall. That almost makes them mobile Linux users.
That in mind, the following web comic explains exactly the difference between the most dedicated users of both platforms. Send this to your resident Android zealot, they will bluster and try to refute it. Happy Friday everyone.
