OS wars are so last decade
I personally do not care. I have worked on (and fumed at) very many versions of Windows, Linux, Unix, Android, and OS-X. I am old enough to have worked on VAX-VMS, RSX-11 on PDP-11 and CDC Cyber NOS (nicknamed either No Operating System or Nasty Operating System), CPM (2.0 and 68K), and more DOS version than I care to mention.
I just want a tool that works. Android works nicely on my HTC phone, and ASUS transformer pad, Windows 8 (with classic shell) works for my kids and missus, and for me in data acquisition behind me telescope, and Linux works on many (non-mobile) machines I need to get my work done. Try processing some of my image and volume data on a mobile device: giga-pixel and tera-pixel range (single images, not a database that size). On the other hand, I don't do web browsing on a cluster. I have considered getting a MacBook Pro as a replacement for my ancient Sony Vaio (lack of nVidia card on their 13" bothered me, not the OS). Different tools for different tasks.
