OP, your sentiments just go to show what windows has done to the computing industry. It's sheer ubiquitousness combined with it's security flaws have convinced people that if you don't have firewalls and virus scanners and malware scanners you don't have security.

When in fact, no amount of scanners and security software in the world can protect a system from a careless or malicious user.

Linux and linux based devices are inherently more secure simply by not defaulting to root level system access to all users.

Add to that the fact that it's not only a linux device, but running a non-x86 processor and you have a very unlikely source for security breeches.

It just seems to me you're overreacting.
