I've been predominantly a Linux user on desktop/laptop since 1995. It has literally never been easier; to install, to use, to find hardware that works (even weird stuff like pro audio devices and oddball controllers), and to act like it's a "normal" computer without having to worry about drivers, kernels, X, etc.

I have had at least as much trouble from my Windows partition and my Android phones as I have from my Linux (mostly Fedora and CentOS) systems.

There really is no longer a credible case to be made that Linux is hard to use on the desktop. I even lend my older computers out to extremely non-technical friends (the kind who don't own a computer) without having to go into any significant detail about how to use Linux; they figure it out in a few minutes, mostly on their own.

If you wanted to make that case even as recently as maybe five years ago, I wouldn't have argued. But, really...the Linux desktop experience today is excellent, certainly comparable to Windows or Mac OS X. And, with Steam providing a huge variety of Linux games, I haven't rebooted into Windows in almost a year (I used to reboot for video projection work, but am no longer involved in that business...I was on the verge of switching even that to Linux, and had I done any more of those jobs it would have been with Linux).
