I use a MacBook. It's my primary (read only one I have powered on ever) computer. I have other computers in the basement, but they don't matter. Anyway, using a Mac is not too different than using a Windows computer in a lot of ways, but people still have questions, mostly because of the way Apples used to be. For example, you don't have to use special RAM, special Hard Drives, or special graphics cards on a Mac, and haven't for a very long time. I could, right now, go buy some IBM memory sticks and throw them in my MacBook, and it would work just fine, (assuming I got the kind that fits my MacBook, of course, as with any computer, you have to get the right kind of memory, but it's not some special Mac-only voodoo or anything.
