IMHO, Mac is much better in so many ways. even though I only used OS 8.6.

I am currently using XP Media Center Edition 2005 (in reality is Professional with a few tweaks). I will say the current version of Windows far exceeds previous versions (and seems to me to be copying Mac OS). The professional level seems to be a lot less vulnerable to the viruses (mine had no problems with the current outbreak, family member's had crashed). I never had one problem with security on my Mac, and i never payed attention to security, had no anti-virus programs. I was young and didn't worry about it.

Mac OS, in short time, will be running on PCs ... They have broken away from HP who made thier power PC processors and are working with Intel. I think the prototypes have it fully running in less than 20 seconds from when you press the power button. Quite impressive, but it is because they don't use any form of DOS, i can't remember exactly but i think image something or another ...

I think it doesn't really matter in the long run, use what you like, what is availible, or what you can afford. The internet is the same regardless, and for most people, that is all that matters. NOTHING will be 100% secure, unless you don't network your computer at all or you have strict control over who is on the network and they are truly trustworthy. A hacker will hack whatever they want, if they feel like it ... not just the easy stuff. Some will find the challenge more interesting, and push themselves to find a way. It is fun for some of them, like a game, not all are out for your bank account.

I still love Macs more, but my XP MCE 05 has definately taken the bad taste out of my mouth that previous Windows OS systems have given me. Still not as problem-free as the mac, but much much better than I had ever expected.
