any way you want to cut it WINDOWS is Mac/Apple. Vista, XP, or any other version it was all taken from Mac/Apple thats fact.
This gets old, so I'll respond once and drop it. Apple didn't invent the GUI and wasn't even the first to market it. The initial work was done at the Xerox Palo Alto Research Center based on earlier work at the Stanford Research Institute and the first GUI based computer was the Xerox Star. There was also a WYSIWYG GUI based program suite called Valdocs produced by Epson. Reports are the Apple was working on the GUI for Mac, and it looked much like the Valdocs system, but after their visit to PARC, the entire look and feel changed to be much more like the Xerox design.
So ultimately, even though Apple fanboys (as opposed to people that just like their products) try to claim that Apple invented the concept, it just isn't so. Apple was the first to market it succesfully, something we've seen them do time and time again. Take existing ideas, refine and expand them, make them work well and give them an appealing style, and then market them. They did the same thing with the mp3 player. There were several on the market (and many of those companies are still making DAPs) prior to the introduction of the iPod, but the market never took off in a big way until Apple refined it.
In the computer and software industries, everyone copies from everyone else, and even though Apple tried to sue MS in the past over the GUI and "look and feel", Apple also got sued by Xerox for the same thing. Both suits went nowhere.
Apple's current OS is based on FreeBSD, a Unix system that they didn't invent (and it's actually a copy of the original AT&T design), and their internet browser is based on KHTML (used in the browser Konqueror) designed by OSS programers for the KDE project (not the first web browser by a long shot, so I guess it's a copy of earlier work as well). New features that Apple has incorporated into OSX were around in other forms (some of them, gasp, in Windows) prior to their introduction into the OS by Apple.
So ultimately, what I'm saying is that there are a lot of ideas around and people use them in their own stuff. Apple does great things, but so do other people, and the really great stuff is being done in OSS these days (and Apple has no compunction about making those ideas their own). The constant everybody copies Apple mantra gets old, when obviously Apple is as big a copycat as everyone else.
Does this mean I "hate" Apple or am a Linux or Windows fanboy? No. I'm a computer enthusiast that enjoys using different hardware, software, and OSes. Limiting yourself to one platform is doing just that, limiting yourself. But computers are tools and entertainment devices (not lifestyles or ego extentions), so if you have one that works for you, fine, use it. Just realize that other people have different wants and needs, and different tastes as well.
EDIT: Got sidetracked and spent a good amount of time reading the history of the GUI (****ed internet just has to much info and is to easy to use sometimes). Anyways, found a couple of interesting sites that may be of interest to people...
