I agree. I just want a system that I don't have to spend sooooooooo much time defending from malware. Most of my friends that have switch to the IMac/Apple are very happy. But many of them still need a Windows based platform to respond to some of the task the military requires of them, such as responding to home family when overseas, or e-mail attachments. But slowly they're weeding out Microsoft, and eventually won't need it anymore."The only thing that matters is how hard it is for me to keep my computer exclusively under my control."
It is natural for a multiuser operating system to have better robustness than an OS which is initially designed with the naive assumption that the owner of the computer will actually be in direct control of all inputs. Even sneakernet communication via floppy disks put paid to that idea. And as for the enormously powerful, thus unavoidable, Internet . . .Mac OS X, as you likely know, is reallyo trulio Unix. Pretty much the gold standard for robustness, in my understanding.
I'm not sure I've seen your handle on Swordmaker's Apple threads, so I'll mention that as you contemplate the switch to a Mac you could do worse than to tune in. That thread is about Mac security and the Skype issue, a good place to start if you're not already on board. In Reply #11 on that thread, Swordmaker advises on how to switch your routine operations account to a standard, rather than an Administrative, user in order to limit the vulnerability of your system.
