Just FYI, for folks who may want to try Mac OSX but don't want to fork over big $$$, you can buy Snow Leopard for $29 (when it comes out) and run it on a virtual machine from your Windows or Linux box with
VirtualBox. It's a free, open-source VM solution that can help some of the unwashed masses see the Mac light. Also, vice versa. My mom is running the Windows 7 RC on a VirtualBox off her Mac OSX machine. Pretty cool stuff!
