Than most are lemons...
The lemon theory is a good theory but not a sound one. This is only one of my many personal experiences. I have been working on Macs and PCs since the beginning and I have to say there is absolutely no comparison of the quality between the two. I admit that I haven't bought or would ever buy a PC that costs as much as a Mac because I would just buy the Mac since I value quality more but I wonder if the systems that actually match the Mac in performance and quality would last as long... Again, it's a gamble I'm not willing to take with the experiences I've had and that others have had. You can buy substandard PCs since you probably can afford to just throw them away and buy another one when it goes out just outside of the warranty, but I don't have that kind of money. I want something that I know will last.
