Umm..maybe I'm missing something but I don't recall reading about a lot of security breaches with Android, outside of some dumb users downloading very shady apps here and there.

Now, you wanna talk jokes, let's talk about the history of Microsoft's products, such as Windows. It is hard to keep a Windows machine going for over a year, no matter how careful you are.

I think, all things considered, that Google bakes excellent security into everything it does.
