No thanks. Having 2 models is good. Just get rid of the MBA as it's just outdated (although I still own mine from 2011). But having a form factors is good have one consumer Mac with option to become pro-sumer and one other Mac that's oriented to pro's and has all the necessary power and necessary upgrades.We need workstations and servers, not a re-release of stuff you just put out a few months ago.
Sigh. Discontinue those air and macbook things, just make one laptop in three sizes from student config to pro user. Nonsense to have 983402 different versions. No wonder the servers and workstations keep getting ignored.
