Linux has gotten a lot friendlier of the years. There was a time, of course, when installing Linux was a bit of chore, finding hardware drivers for it was even more difficult and installing programs was a nightmare.
That has largely changed. Take Ubuntu Linux, for example. That installs easily, contains most of the drivers anyone will need for their hardware and even comes with enough programs installed (an office suite, graphics package similar to Photoshop, etc.) to make it useful immediately. Installing programs is easy to through the built-in Ubuntu store. Oh, and most programs are free.
Now, there are some drawbacks. Some essential programs simply won't work on Linux -- Adobe InDesign and Intuit Quickbooks, for example. Also, there are some things you simply can't do without opening up a terminal and banging in commands on a UNIX-like interface.
Still, Linux has come a long way.
