But it baffles me that anyone would want to see Apple remove a significant part(do not compare this to an optical drive, which really isn't used, and can be bought for like $30) of the MacBook Pro and force users to spend hundreds of dollars MORE, on and external solution. Makes no sense.
That's exactly what they did the Macbook, except ports are mandatory and a dGPU is not (you can skate by on an iGPU on the road and use the TB3 at home).
