I bought my current rMBP in late 2014, and it may well be my last Apple product... I&#x27;ve mainly been a fan because of the ootb unix support, and the touchpad (that&#x27;s a huge deal for me).  The screens are nice too, but others have caught up, and I can&#x27;t see detail that well anymore.<p>The SMB&#x2F;CIFS change from samba is what caught me, that was kind of painful.  I finally upgraded to El Capitan, and not sure I like it much better.  For the most part, OSX is the one that stands out in terms of how I use my computer... Ubuntu and Windows are closer to each other (with bash) than OSX, and once windows has native Linux subsystem in general availability, I may wind up using it more.
