The response to this trend has always been the continued niche usage of Linux OS outside of server environments. Based on the quality of software applications, Professionals really have only two alternatives: Windows and Mac. I've always went with Windows because I don't engage as heavily in the creative process (music, video, design, etc.) that would benefit from a Mac. At worst for Apple, Professionals return to Windows laptops (Dell, HP, Lenovo, Microsoft, etc.) - that's a loss of 5%, maybe?
