Developers are the core customers for MacBook Pros. In volume the Air used to be the top seller, because yes there are more people who just want "a computer" that works and don't care about specs and won't look at battery life, etc. before buying.
But do you know what those people base their purchasing decisions on? The recommendations of the developers and engineers they know who do care about those specs.
I can't tell you how many people have moved over to Apple computers on my recommendations over the years. It's a lot. Right now I have a hard time recommending the 2016 models. If people can get a refurbished 2015 on the cheap I honestly think it's a better choice.
> After 5 days, it was already crushing the competition and approaching 18 months of Macbook 2015 sales.
This statistic is very popular but it's also extremely misleading. Everybody knew the lineup was due for a refresh so 2015 sales were lagging because of that, the higher numbers represent a dam of pent up purchases waiting for upgrades bursting. It's like pointing out that the number of people complaining about the 2016 models is way higher than the people complaining about the 2015 models. Of course it is. That doesn't tell the whole story and is somewhat misleading on its own.
My point is just because initial sales of the 2016 models is high, doesn't mean that it will stay that way. Once they get into people's hands and people find out "Oh the battery life is terrible and I really don't like the TouchBar." those sales may plummet (if that indeed is people's reaction.)
Apple needs to really re-examine. The current 13" and 15" MBP models should be the base "MacBook" models, and they should come out with a serious pro machine and label it as such (which restores MagSafe and has higher battery life.) The TouchBar should just be thrown off a bridge. It's a terrible gimmicky attempt at stuffing a touch screen onto a laptop.
