I was sad when S.G.I.s died out, never becoming a paradigm for Apple or P.C. development, but I'm seriously going to weep if Mac OS gets "phased out". That will be the day that all beauty (or whatever beauty there was) in the machine will vanish. It's like Windows are explicitly against any interface improvement or enriching the user's experience beyond that of brute performance (as is asserted). Most programs that were developed for that operating system, even when "translated" for the Mac, they reek of their aesthetic origin. If computers were merely number-crunching boxes I could care a lot less. However, if I have to stare at a screen environment all day and interact with it, my aesthetics are almost as paramount as performance - I don't see why I can't have my cake and eat it in this regard.
Be that as it may, I'm scared that Apple is turning its face away from the artistic professionals it proudly served for the past 25 years or so, and towards silly women and lower management executives who buy iPhones and iPads, because they are the "In" apparel accessories of the "times" (frequently being incapable of using any semi-advanced function those accessories offer), as well as teenagers who see them as toys and media sharing devices (be it their own skating-videos, or pilfered MP3s). If Apple's future lies in i(t)OS, iChat, and iShat, maybe Jobs did die at the right time...
