I both agree and disagree. First - where I agree is the relative price of MBP due to TB. I agree the difference without the TB would be $100 at maximum (note that Apple may decide to offer a, say, $300-500 cheaper 15" without the TB, but it would most likely come with a lower clocked CPU, worse GPU, smaller drive, etc - this difference would not be due to the lack of TB).
My point here is that a lot of people on this forum seem to think that the MBP would cost just as the old one (as it did in 2015) if Apple didn't include the TB. I am convinced that is not the case. I believe Apple had a price (plus that 30% or greater margin) set from the beginning, then just built the best computer they could (or believed to be the best) around that price.
Nah. The cost of technology comes down over time.
Pretty sure that Apple raised prices on the 2015 13" Macbook Pro (at least in the AU store) while it was still on sale (not sure if it still is, but it was for some time after the touchbar machines were released). In order to replace my 2015 machine with the same spec machine in 2016 would have cost me more money (i checked). For an identical machine.
Even more money if i wanted equivalent tier in the model lineup at the time.
I think Apple are trying to force people into the ipad Pro instead.
