I've been working with a MacBook for about three years now, and it is my most favorite laptop. I call her Stacey. There are far fewer system issues, crashes, etc, than I've had with PCs, and in the event that something does go wrong and I don't know how to fix it, AppleCare is infinitely easier to work with than Microsoft support. A little pretentious, but ultimately more helpful.
I'm not a big Apple fan brand-wise, I don't use an iphone or ipad or any other Apple tech, but Stacy and OSX have been doing me just fine. The major drawbacks most people run into are the price, which is irrelevant since yours was a gift, the gaming capabilities (which doesn't affect me much, I'm definitely a console kind of girl), and the incompatibility with Windows-originated files or programs. And to that I say: In three years of mac usage, I have never encountered something that I couldn't run on my macbook. If the capability doesn't come naturally, there's *always* a free program online that makes it mac-friendly.
