I don't mind the move to USB-C, as long as it is the latest version (integrated with TB). The industry is moving that way, and the less proprietary Apple becomes, the better. If there'll be "one port to rule them all", this is it.
That said, I just don't see the need to "upgrade" from my 2011/2012 cMBPs, including my beloved and trusty 17. Every single machine after those has been neutered in some way, and Apple is quickly turning all Macs into sealed, un-upgradeable, dongle-heavy fashion accessories.
I personally find the proprietary SSD particularly egregious; storage is something that should be upgradeable in ANY computer.
I'd love Apple return to form and split the consumer and Pro lines more distinctly, and offer more options for each. But it looks like it just isn't going to happen. Instead, Apple is moving towards convergence.
The whole "simplicity" philosophy just doesn't work here.
Thus, Apple is putting ALL their eggs on iOS and the stupid Watch. (Real) Macs don't matter. Fashion is the VISION in this new Apple. Angela Ahrendts was brought in for a reason.
It all makes me both sad and angry, but hopeful that the competition will deliver something I finally can say "yes" to in the near future.
I'm glad I found an iOS/iPhone alternative in Android-land. Things are harder on the Mac-side, however.
