The new Retina systems are closed, no ram or SSD upgrades; Why. Can someone explain the advantage of this. I can see the marketing side when you make a solid product that can last 10 years. You need to generate churn in product. A closed System can churn more profits on the front end and down the road since people cant upgrade, they need to buy new. But can that be the primary reason? Well you could say that people installing inferior RAM or SSDs are bringing down the product image.... Wrong - it enhanced people to invest in the Mac product line since they know it can be updated if needed.. Ya no it would be so simple, just put two hatch doors and allow us to snap in memory and SSDs. In my mind, Apple should want more people to own Mac's because then they will come back. Apple could also shave off some profits, reduce the price point and in a decade windows machines would be like VHS. I am relatively new to the I-world and have quickly fell in love with it. However the trickle of features and restricted add-on/upgrades baffle me.
