As detailed in this thread, I'm considering moving away from 10.9.3 on my 2011 base mini, because Time Machine can apparently no longer use my old NAS. So, if I move to OS X Server, it will strictly be so my wife can use TM backup to my mini + DAS, instead of my NAS. Question: am I giving up anything moving to OS X Server, that I would normally get via Mavericks or eventually 10.10.x? I like and appreciate the small changes Apple gives us with the minor updates. Is Server updated just as regularly now, with all the standard OS minor updates? Should I just wait a few months until they release a Server build based on 10.10.x?
