wow... Will this ever end?
I look at it like this. To compare Macs and PC's is comparing apples to oranges.. Apple builds macs.. and nobody else does.
PCs are built by HP, Compaq, IBM, Dell, Gateway, Acer, Alienware, Toshiba, the list goes on.. Not to mention all the generic whitbox stuff. When IBM released (or lost) the patent on the PC and the rest of the world got the chance to build them things went down hill... Back in the day when Hewlett Packard was supposedly building computers out of used parts, you could buy a biostar motherboard for $29 , everyone was trying to build a cheaper IBM computer. and they did.
PC's are like lawnmowers, no matter what the name plate says theres still most likely a briggs & stratton, or a Kohler or Tecumseh engine under the hood. But you could go buy a cheap plastic wanna be mower from The hardware store, or go buy a john deer (yeah now they make cheap crappy deeres too) But thats my point.. You get what you pay for, and if you go buy a $399 compaq laptop from the store and its got some flimsy hinges, well thats what you paid for.. or go buy a Sony Vio and spend 4-5 times as much and get a much sturdier machine... they still have the same components inside.. Intel, or AMD.
I dont particulary like Vista, and Xp has come a long way from what it once was but, I dont think any OS id better, Windows or Mac OS. People say that the MAC os is a lot more stable, and has less chance of being hijacked, or attacked by viruses online, and they do, But is it because they are better? i dont think so.. Most of the individual users on the internet are PC users.. Most all big coroporations online use PC based systems running Windows...
Hackers want to make the biggest impression possible, they hope to create malicious software to bring down as many systems and users as they can, and those users are PC users.. They would rather target windows systems to get the most bang for their buck, rather than put hours into writing code that might only affect the 5% of the internet that uses Mac OS. When big businesses start to use mac stsyems rather than windows based systems we will all see a HUGE increase in number of malicious mac attacks..
Bottom line is this:
With a PC you can get a Throw away model or a Mercedes Benz
With a Mac, you only get one choice... The apple.
