So, basically, make it just like Windows?
Not necessarily, because GNU/Linux distros work pretty much the same deal such as quiting a window upon clicking the red x, maximizing the whole window, having a file management system which sorts everything alphabetically starting with directories at the top, and some GNU/Linux distros have some sort of cool desktop environment like in Fedora with KDE.
I'm a switcher, but I've also been using GNU/Linux distros as well before the Mac and one of the things I've noticed about Mac OS X is that it is quite powerful as an operating system, but not so user-friendly and/or looks plain. Just the default grey color of the menu bar and windows reminds of MS Windows 95 - 2000.
What I'm trying to say is that Apple has no taste in their desktop environment, it looks plain. The only way to change it is to modify a sorts of things instead of having some nice app that easily allows you to change themes, once again just like in Windows or GNU/Linux distros.
And from the looks of it as others have state it, Mac OS Lion doesn't seem much at all from Snow Leopard. I'm hoping it's not, but then again look at Leopard and Snow Leopard, pretty much almost the same. Most of anything was just under the hood changes, like all re-written OS to 64 bit.
