Since you have NO EXPERIENCE with an operating system that has been in use for 4 years, what are you doing on this thread spreading your ignorance? You make sweeping statements about connectivity, "not playing nice", and Macs having "issues", speaking ex cathedra, claiming "networking" expertise, when you have no experience from which to speak... and arguing with those of us WHO DO HAVE THE EXPERIENCE and the expertise.
Be happy that you have a tiny market share so you don't get spyware written for them.
Your citing the myth of "security by obscurity" demonstrates again your ignorance of the basic security built into to BSDUnix and OSX. In four years no one has been able to create a self-installing spyware/adware program for OSX. Yet you ASSUME that it is merely that the programers who create such vileness just ignore the Mac market because it is less than 4% of the market. That canard has been shot down many times... and the evidence is that there are, as yet, no candidate programs to prove it can be done.
You admit that you have not even had a "close up look" at a modern Mac, yet you feel comfortable advising people as to their suitability for various uses. That is arogant and willful ignorance. It has become apparent that "what you know" is based on hearsay, antique information, or myth.
