So what's so great about MACs?

I've had an IBM laptop for 3 years. Its a T-42 Thinkpad with Windows XP. I've never had a problem with it. I use Norton Internet Security and keep it up to date.

MACs are more expensive and require additional steps to run window's based programs. Yet everyone I fly with either owns or is planning to buy a MAC, iphone, etc. Is it something in the coffee or am I just missing the bus???
