Wow 20 voted yes, wasn't expecting that. I'm a long-time PC (i.e. x86) user (aren't Mac's
Personal
Computers as well) my sig, in a nutshell, explains my reasoning. As I said, my interest is increasing but I still think Apple has a way's off before it will peak.
In my opinion here is what Apple has going for itself:
- Design is top notch
- Power of Unix made easy
- Aqua is well designed and intuitive
- Warrenty and tech support is top notch (so I'm told)
- Quality of hardware is top notch (so I'm told)
- Quality of software is top notch (no argument from me here)
- Software support is almost a non-issue (I explain below)
- Hardware performance is a non-issue
What Apple doesn't:
- Support for games
- Support for newer NVIDIA device drivers (think this is solved)
- Support for Surround Sound (at a reasonable price damnit)
- Overall price
- Some Mac patrons will, at times, exaggerate or even make-up problems they've had on PC (x86) machines. I'm sure some PeeCee (I give up

) patrons do the same but why bring yourselves down to their level.
Please keep in mind that my opinions are based on what I use a computer for, how much money I have, and my past experience. My main requirements for a computer are stability, security (reasonable not paranoid), works with the software I throw at it, and doesn't give me any problems.
My current setup meets my needs and then some. It's not top of the line but suits me. I'm not really partial to either platform and to me Windows and Mac OS are interchangable in the big picture. Sorry if that offends the Mac zealots out there
Well I suppose I haven't answered the question as it looks to be meant towards Mac users that also might use a PC. Ahh well.
