re: Someone explain Linux to me?

Linux is very flexible and in the last several years has become the base of an operating system that millions of people use every day, but may not realize it.

Android runs on a linux kernel.

Most major websites run on linux.

OSX is pretty much a Mickey Mouse interface on top of a custom linux.

More people should use it on their desktops that all they use for is web, email, etc, there would be a lot less infected computers.

As someone already said, it's usability in say a business environment is limited because it won't run a lot of business software. I didn't really care for the way it was worded, though. It's not like someone wrote those business applications, then Windows wrote their OS and it could run it, but linux wrote it's OS and it couldn't run it.

The reason linux doesn't run those applications is because those applications were programmed to run in a Windows environment.

If more commercial applications were written for linux, I think it would take the world by storm.
