I just went to Office Depot and Best Buy and say a few flavors of Linux right beside Windows OS's. I wouldn't exactly say XP and Vista are the only OS's you see in stores.
Your comment interests me...
I'm into both of those stores on a regular basis, and the only Linux distribution I've seen was Xandros at Office Depot. Nothing at Best Buy. I just checked their websites, and it's the same. Xandros at Office Depot, and nothing at Best Buy. And there's a reason why you don't see Linux desktop distributions in stores. They're free.
The top ten desktop distros for Linux are listed and described here:

The choices I see in stores are the various versions of Windows, and Apple, though the "box" their operating system comes in, is a bit more expensive that the cardboard boxes Windows Vista comes in (read that - you have to buy the computer too).
All distributions of Linux are free (as in freedom). Read here:
http://www.gnu.org/philosophy/free-sw.htmlThough free (as in freedom) does not necessarily mean free (as in price), ain't it great, that the top ten desktop distributions for Linux (including a version of Xandros), are also free (as in beer).
Edit:
Forgot to mention...
The reason that there are so many Linux distros, is that free (as in freedom) thingee.
Free (as in choice) is a wonderful thing!
