Change the statement to "OS X has better hardware support on the Mac" (and conversely Linux has better support than OS X on everything non-Mac) and there would be no need for this article. One's a walled garden - albeit I am glad that it's at least a POSIX garden - and another is a truly open platform running on every hardware imaginable. It's like saying iOS sucks on the Google Nexus or Android sucks on iPhones.
Right, but people don't make that argument, they say "I'll switch to Linux when it has as good of hardware support as OS X does." At least in my circles.
