Most recent Macintosh OS is limited to only the most recent Macs. THIS MEANS THAT THEY DON'T LAST LONGER - YOU CAN PUT WINDOWS 8 ON A 10 YEAR OLD PC! (Theoretically)just about the only thing in this that is true is that macs are more restricted but are more secure. they will always have the latest and best quality parts, even if they are not the most powerful. that is part of the reason why they run so good for what they are and last long.Believe it or not, Macs are the same as low quality Microsoft machines in almost every way. They charge a fortune just for the packaging, even though the hardware is completely the same. Amcs are also the most secure computers in the market, but incredibly restrictive. You are paying extra for slightly more protection by removal of priveliges.
YOU CAN'T REPLACE PARTS ON A MAC!
YOU CAN'T INSTALL UNSIGNED CODE ON A MAC, WITHOUT VOIDING THEIR WARRANTY!
YOU SAID "they will always have the latest and best quality parts, even if they are not the most powerful"... THIS IS THE BIGGEST OXYMORON EVER, ESPECIALLY FOR THEIR PRICE!
THE REASON MACS ARE SO "SECURE" IS NO HACKER IS GOING TO TAKE THE TIME TO CODE A VIRUS FOR A MINORITY OF COMPUTER, SO WINDOWS IS ESSENTIALLY ALIENATED FOR ITS SUCCESS. THIS DOESNT MAKE MACS MORE SECURE, TAKE ANY APPLE MOBILE DEVICE, MOST OF THEM ARE JAILBROKEN, THUS DISPROVING YOUR THEORY THAT APPLE'S CODING IS IMPERVIOUS TO MANIPULATION
VERY SAD THAT YOU ARE STILL DEFENDING APPLE'S SHOCKING BUSINESS PRACTICES...
