If mac users are so proud of macs, how come I always see windows installed on them??

I have nothing against macs, but people are always telling other people to get macs, etc, because of how great a mac is. The OS is so good and easy to learn etc. Then next thing you know, they also installed a copy of windows on their mac (whether they really use it or not, i don't really know)
For If mac users are so proud of macs, how come I always see windows installed on them?? try this:

• Sometimes a *necessary* piece of software is written *only* for Windows. (The developer of the software hasn't been considerate, or doesn't have the skills, or the time, to develop a version that runs on the Mac.) I have a few programs like that.
  
  Take also, my case. I do websites. Not everyone in the world uses a Mac. I can't develop websites just for Mac users. I have to test on Windows to make sure they look good there, too. The alternative to having two PCs (like, at $2000 for a Windows PC?) is to have a copy of Windows running on the Mac (at like a tenth the price, all told?)
  
  Finally, I'm just now migrating...I traded in my PC for a Mac, and am getting rid of my Microsoft "addiction" (that needle in my arm...), but I'm not an IMMEDIATE expert on MacOSX (like, I'm not omnicient, ya know! and I can't just quit "cold turkey") So I need my copy of Windows to lean on for just a little "hit" now and then (snort, snort).
  
• maybe windows is more popular than mac os so everything runs on windows but not on macs, so, maybe they do that just if they come across something made only for windows then even be able too use it
  
• the reason been you can do much more with a pc than you can with a MAC
  
• Some software is only designed for PCs because there is a bigger market of PC users. The only way you can use those programs in a Mac is by running Windows on it. I have a Mac, and I would much rather have those programs available for Mac OS, but companies are too lazy.
  
• Hi, well Mac users always need programs and games for running which only work on Windows. I noticed this as well, my father has a macbook but he hasn't installed windows on it but everyone else I know with a mac has. Also haven't u noticed that Vista aero interface is like a million times better than Leopard's plastic metal aqua interface, Mac users no doubt like it.
  
  Myself I use Linux and I think as well that Linux is better than both Windows and Mac OS X.
  
• I have often wondered this. One thing is for sure is Linux is superior to both.
  
• The only people I know who have Windows installed on their Macs (and I know a lot of them) have it there so they can test webpages they write in Internet Explorer. They do all their actual work in native OS X applications.
