I don't have major issues with Linux. I've had a few teething problems with new hardware and occasionally there's a surprise, but nothing like the author described. In fact, for me, GNU/Linux is more of a pleasure to run than any other operating system I've used, including OS X. Having said that, I had major issues with Linux when I tried to make it my primary OS for the first time in 2006 and can empathize with the author of this article. I had such a bad experience that I went back to Windows XP and didn't make the full switch until early 2010; I haven't looked back since.
If anything, this article is a call to action to improve desktop Linux. We're all aware of the second class nature of consumer vendor support, and there are a lot of native apps that don't compare to their OS X or Windows counterparts, both in functionality and aesthetics. (GIMP comes to mind. It's ok, but it's nowhere near as capable as the current version of Photoshop.)
