Before considering any opions on the Mac you've got to realize there are differnt kinds of Mac users and you need to be careful who you listen to.
The knoledgeable: Users you can put on any computer and they'll be productive. These are the guys to listen to
The itards: Barely know how to turn on a computer, can barely spend five minutes on a windows computer without doing something to

it up, and it's all Microsoft's fault their idiots. The only use the Mac features that were designed with 3 years olds in mind and because of that have a very unrealistic view of things. Their advice on anything including non-computer stuff should be ignored.
The fanatics: They gave up on reality a long time ago. More likely to tell you that Macs cure cancer than tell you anything useful. For the sake of humanity ignore them and pretend they don't exist.
That said, for when you mentioned a Mac would serve you well. The thing is that a much less expensive PC would as well. Here are the factors you should look at when making your decision.
1) Have you ever used a Mac? If not don't consider anything until you use one. Some will swear by the interface, I think the dock is the source of all evil in the world. You won't know if you don't try it so either find a friend that has one or get your ass into a Mac store
2) Do you have specific software you need to use? If so make sure it's available for Mac and if you already have it, realize you will need to repurchase it. Yes you can bootcamp windows, but that will add to the cost of entry, and doesn't it kind of beet the point of a Mac
3) What do you really need? Do you really need a Mac or not. These days they are both capable of the same things, so is it worth spending possibly a good bit more money for something that isn't much more than a status symbol? Unless you have a specific need for a Mac or buying something that screams "please think I'm cool" is what you're looking for, it might not be right for you. The key it to make up your own mind.
