As someone who has to fix loads of pc's (including an ancient Pentium 1 tonight
) the it's definetly not just osX that makes the difference.
The hardware is generally (in my experience) far far more reliable.
It's generally a masterpiece of design and precision. Look inside a powermac G5 and then look inside a Dell Dimension and a world of difference and production value is clear.
And while aesthetics, may seem a shallow argument for pc or mac, trust me if your sat staring at a computer every day of your life like I am, I'd rather be doing that with somthing that looks right, feels more comfortable and doesnt sound like a cheap plastic vacuum cleaner...
Operating System is the killer though.. Once you have tried, and got used to (it will take you a few weeks) you will never go back to Windows....
There's so many intricacies and differences that make osX better it would make this thread too long to go into if we were to list them all.
Yes PC's have some benefits. More games if your a gamer, generally more choice of software.. Not necesserily better software, but more choice definetly...
However if like me and many others on this forum, find everything you need to ever do on a computer can be done on a mac, then windows soon dissapears into a faded hazy memory....
