Absolutely false. Desktop Linux is all except great. As they already highlighted in this thread there are plenty of annoyances and it is on the whole a subpar experience compared to Windows and Mac OS X.
In windows and Mac you can use the same terminal if you want, but you are not forced to use it.
There is no way for me to switch to Linux, Mac OS X gives me exactly the experience that I want, without headache.
I don't care if people don't use Mac OS X and so I'm pretty annoyed when there are people that try to push others to switch to Linux, like in this article.
Enjoy your Linux, but please don't write untrue absolutes like "Desktop Linux is great".
