Tell that to my wife who works in the graphic design dept at a local publication and has had her Mac Pro go nuts on her often enough she has more than once wanted to toss it out the window (the metal bars on the window would stop her though
)
As an IT guy who manages multiple flavors and versions of Windows and Linux as well as multiple mobile OS platforms, I can guarantee you this:
* Expecting any OS to be perfect is naive. You want a perfect OS, stick to a calculator or digital watch.
* If Mac OS was impervious to viruses and malware, Apple wouldn't bother updating regularly. There have been 10 mayor security updates released from Apple this calendar year, nowhere near as many as Microsoft has released, but they exist and at times these updates are quite hefty in size.
* BitDefender, one of the top antivirus/antimalware software vendors just released a Mac OSX product that targets "270 specific threats," most of which seem to be browser and networking related.
* Are Macs less likely to have issues than Windows? Usually yes. Then again I've had production machines running Windows and Linux run for years without issues.
My philosophy is simple - if it works for you or for a task, use it. If you enjoy using it then it's all the better!
This whole entire argument about which OS is better is as productive as forwarding 100 emails because someone promised if you did, you will get a free restaurant gift card.
