And also, you can buy right-button mice (and even scroll-wheel) mice for the Mac, and they should work. Unfortunately, not all software for the Mac has adapted to being used by a right-button mouse, so you might still have to ctrl-click in certain programs. In addition, the operating system itself isn't quite as adapted to using the ctrl-click as the Windows OS is adapted to using the right-click, but it still can be useful. For example, if you're a hacker or a programmer, you can ctrl-click on certain files (mostly packaged programs and stuff, sometimes programs) and one of the options you might get is "Show Package Contents". If you do, you'll access a lot of hidden menus, containing the stuff that actually makes up that program. You can open certain stuff in a text editor (like TextEdit) or Terminal, and edit the text to actually change stuff within the program. For example, you can lower the system requirements. Of course, you HAVE to know what you're doing for this, or the results could really be BAD. Therefore, unless you're an expert on this stuff, I wouldn't recommend it. But, that's just one usefulness of ctrl-click that even the right-click on PCs doesn't have!
