Today is the day that Windows 10 will be installed on the computers of those who signed up for the upgrade and are at the front of the queue. If you didn’t know, anyone currently running Windows 7 or Windows 8 can get a free upgrade to Windows 10. You can find more information about how to do that here: http://www.microsoft.com/en-us/windows/windows-10-upgrade
Of course there are other operating systems out there that shouldn’t be forgotten. If you’re an Apple user you will be familiar with OS X and iOS. You may also be sitting back thinking it’s funny that a free OS upgrade is such a big deal since you’ve been getting those for a while now.
But there’s another operating system out there that doesn’t get much attention from the average person. Chances are good that you’ve either not heard of it, or have heard of it in passing but don’t know much about it. Believe it or not, we’re actually surrounded by Linux systems. The Android operating system used on so many mobile devices is based on Linux. Also, if you look at the operating systems used by Internet servers and supercomputers, the vast majority run on Linux or other Unix-like operating systems. Check out the numbers here: https://en.wikipedia.org/wiki/Usage_share_of_operating_systems
Linux was created by a worldwide community of programmers. There are those who don’t think that an operating system created by a nebulous group of people could possibly be any good, but those numbers from before would tend to indicate otherwise. But don’t take my word for it. Why not check it out for yourself sometime? It’s freely available to download and many of the programs written for Linux are free as well.
So on this, the day when the first people will be getting their shiny new copies of Windows 10, I encourage you to learn more about your OS of choice and some about the alternatives. You never know, you may end up with a new favorite.
