You're going to get diehards on both sides of the fence. Coming from a Windows users that has had a decent amount of experience with both, I'd say they are both going to be right. As someone else said, it's ultimately up to you. You may find it's the greatest thing ever. Or you may find you hate it. Mac vs Windows definitely takes some getting used to, and you may not like it at all.
One thing I will say you should consider: how long do you wait between computers? Do you repair your computer and repair your computer and repair your computer until you have no choice but to buy another? If so, the parts for Mac are often more expensive than the parts for Windows computers. Also, they are hard to work on, esp laptops, and may force you to take it to a repair shop if you aren't well versed in computer repair (perhaps by design?).
I personally don't know what kind of warranties that Macs offer, but I swear by the Dell warranties (get the covers-absolutely-everything warranty).
