Moving to Mac

I ordered a Macbook Pro today to serve as my work machine. My experience with Apple products to date hasn't been so hot. I'm really hoping that this time is different. I'm doing this because I'm constantly frustrated with Tomoko's machine and I'm not familiar enough to do anything with it. I'd like to learn how to use one as well as I know how to use Windows. Seems they're getting more and more popular and everyone else I talk to swears by them. I'm actually hoping I'm a convert.
