Macs are more intuitive and user-friendly

It only takes a few hours for anyone to get familiar with a Mac. The programs that come pre-installed on a Mac are easy to use, powerful and have well-polished interfaces. "Nice looking graphics" however are only one aspect of the package. The included software is efficient and works better than the included alternatives in Windows, and often outshines even paid alternatives.

One person's opinion on user interface does not reflect the general consensus. Most people who find Macs hard to operate are those who don't want to get used to anything that differs even slightly from what they are used to already. The minimize problem is a great example of this. On windows, the close, minimize and maximize buttons are located on the top right corner of a window and marked with x, a dash and a square respectively. On a Mac, these buttons are located on the top left and are colored red, yellow and green respectively, thus mimicking the more intuitive traffic light pattern. (When a user moves the moves over these buttons, they display an x, -, and + respectively.)respectively.). 
 
Besides, the Mac's GUI is so popular and loved, that Microsoft have stolen/copied it. Windows Vista and 7 are a proof of that. All the new in their GUI's is a copy of Mac one, but rotten and corrupt, a wrong/bad copy. Two example, in W-Vista the Sidebar Windows is the same thing that Mac Widget, but it use more computer recourses and have a "Bar" even if you display your gadget across all the desktop. 
 
It's true that there is several programs and games only Windows Compatible, but there aren't few for mac users. A Mac user can find anything for his/her needs.

"It only takes a few hours for anyone to get familiar with a Mac. " I must disagree with this statement. As a film student, I have been using Mac for film editing for years, and I still haven't gotten used to browsing files, switching applications and otherwise working with Macs.

I personally feel that the Mac OS X interface is bad. It's just liked mostly, because of the nice looking graphics.

I find switching between applications terribly hard. And then when it comes to switching windows in an application, even worse! And don't even get me started on the button that should be maximise, but isn't!

For an end-user i think Windows Vista is a more powerful OS. There are a lot of programs and games which are only compatible with Windows platform.
