Because.... 'innovation' I guess. The argument I keep hearing, is that we're just not the target market for Apple any longer. I guess we'll see what the Mac Pro is like, but it sure seems this is true. The new MBP, iMac Pro, etc. seem designed for a different kind of pro user than in the past. I've said this before.... but Pro used to be a quality about the machine. It was professional grade hardware. More fault tolerant, better cooling, better components, faster, etc. Now, it seems to have to do more with an upper-class categorization of user. You know, it's the model for the entrepreneur or lawyer instead of the student or home user. In other words, someone with more money, likely to buy an up-sell. Or, marketing driven vs purpose driven.
