Hey, may be we shouldn't have computers connected to internet, because you know "Hackers"!!!
Seriously, what's with all this paranoia? Yes, mobile OS vendors have probably been lax until now, and once vulnerabilities are found, they will clean up their act, or they will be overthrown in the market by someone who does a better job. Windows used to suck, but now it's much better. I'm sure Android will get there too. That does not mean, we can give them a pass for security vulnerabilities. We should absolutely hold them accountable and publicize the issue so that they know that's not acceptable.
Now, I will get off your lawn.
