One of my friends is a staunch supporter of Microsoft products.
He was really impressed with a friends new phone, a Droid running the Android OS.
I informed him that the OS (Operating System) he was impressed with "Android" is a version of Linux.
I am seeing more and more people interested in linux, besides the price for linux distrobutions usually being free, there is also the ability to do almost everything windows does, with the exception of a few 3D video games and a few windows programs.
I think your going to see big things come from the Ubuntu and PCLinuxOS versions of Linux.
I believe we will soon see a Linux OS that can run 100% of all windows apps.
What that would mean to someone that chooses linux is that they would be able to run all windows apps, all linux apps, and a lot of, if not all of Mac's apps.
(An app, short for application, is a program. anything you run, from notepad or word, to a video game is known as an app.)
