Apple being biggest muscle in the industry should educate people to prolong their macs life by adding more ram after few new versions of OS. Instead they milk money from people throwing their macs away every other year. And then Apple tells us how green they are, with all recycling and stuff... Ridiculous!
If Apple built cars, you'd have to pay premium to change tires...
Throw away?!?!
Seriously everyone I know who upgrades yearly is the head of a food chain. Either at work or in family that let's them max out their Mac knowing it'll be in use for up to a decade at least. Why would you throw it out when resale is a short email or facebook away.
Only problem is it makes you the family "IT guy"
