I hope it's not already been observed (I'm not reading through the posts to check), but it's interesting that Linux overtakes Mac OS, and both combined approach Windows (without even adding IOS). Having been forced to 'upgrade' to a Windows machine at work (Lenovo Thinkpad E14), I can see why there is a preference for alternatives. IMHO, Windows is just layers and layers of duct tape. At least the Linux and Mac developers have tried to produce viable OSes from scratch. When I burrow down in Windows I eventually see 'just good enough' code that hasn't changed in decades. I'm not trying to burn the Windows lovers here, but if I didn't have to use it (because of my employer's mandate and a few important Apps that don't run natively on Mac) I would hurl it into oblivion. Yikes.
I would also miss some truly impressive Mac-only Apps. For productivity, Devonthink, Mellel, and Bookends, plus the Pages/Keynote/Numbers suite. For fun, the Rogue Amoeba apps (Audio Hijack and Sound Connect). This is not to say that Mac is a cakewalk or that many things haven't gone somewhat downhill since Jobs passed (keyboardgate, bendgate, etc.).
To each their own and YMMV etc.
