Re: To Linux users
For any of the most popular distributions of Linux, you will feel right at home. I'm currently using Linux Lite (what you should install on crappy, old computers) and it is pretty much just like Windows, but without direct compatibility with Windows software. If you are new to Linux (like me!) I'd suggest any distro based off of Ubuntu. Even the standard Ubuntu, which has a different graphical interface concept than Windows, is really easy to just load up and start clicking away.
For the basic tasks, you can easily jump right in and start using it on day one as if you had been using Linux your entire life. The main difference is when you get into using command lines and/or doing network administration, which it doesn't sound like you plan on doing. Either way, there are a shit-ton of forums where all you have to do is copy and paste what some more knowledgeable nerd posted at one point in time.
I changed my signature. Not that anyone cares enough to notice
