For me, logic works like this:
1. Windows has always been victim of viruses cos it was the most important OS for so many years (and with the most users)
2. Mac users are now becoming the new victims since Apple = $$$
3. Android might not mean as much $$$ as the iPhone industry, but.. we are growing at a very, very fast and steady rate.
4. Android might be safe nonetheless, since most hackers can't write code for Linux and... if they can, they are Developers, not hackers (anymore)
5. Only 1% of the malware has come from Google Play
6. Since most of Root users (or jailbreak users) aren't into paying for every single app/game they use... (I have paid for like 40 pieces of software, but I use more than those -not at the same time, though-)
7. Anti-Theft features are nice to have in hand
8. As most people say, better safe than sorry.
But, I guess point #4 is enough explanation why I feel safe xD
