Almost all of that goes out the window for targeted attacks. For general safety, you just need to be a little bit better than the average computer user--the money is in simple reliable attacks that hit broad swaths of the public. But for targeted attacks you need to have near perfect security. Edit: You're probably still gaining by leaving the beaten path, but if you're exposed, and someone knows what you're running and has the resources to create custom exploits, that won't help much.
