Apple has never been known for it's quality. Your statement about A+ quality components and MTBF (HBF as you say it) is hogwash. Please supply some real sources to back this up.
No viruses or exploits. Then why is there Antivirus software and system patches? No system is perfect, they all have flaws.
The only reasons that Macs cost more than equivilent PC are: 1) people are willing to pay, 2) Apple has a hardware monopoly, and 3) Apple uses illegal price fixing strategies to eliminate dealer competition.
