I was going to wait for the fall release but I was able to unload my old machine at a very good price so I am looking to buy one in the interim. Then my plan is to assess the new one (if it's even announced), and then decide on buying it. Apple stuff is so easy to sell and I don't care about losing a couple hundred here or there in the sell/buy process. Now I'm buying a late '15 3.3 i5 M395 512 SSD This is the setup I originally wish I would've boughten but I took some bad advice and bought a "CrapMac" 5K. anyway My question is should I get the i7? What is ACTUALLY the difference for someone who is just using this as a home computer? Would my user experience be much better? It seems enticing but I'm wondering if it's even necessary.
