I can sum up the difference in one word:
Intuitive
PCs are difficult to use, they get viruses a lot, they slow down, crash, and crawl to a halt, and things aren't always where you expect them to be. They aren't "logical," despite all of the advancements in home computers.
Macs are intuitive, which is why they're easier to learn and operate. If you don't know where something is or how it functions (I don't mean fancy software, but basic computer stuff), you can almost always figure it out by logic and intuition. They "make sense" to computer users, and that's why people have a much better experience on them. It's well worth the added cost.
Going from PC to Mac is easy. The learning curve only lasts a few days to a week max. Going the other way, I've seen people freak out. Mac users who had to use a PC. Their heads usually explode and they take to drink quickly.
