The PC industry as a whole is declining from a sales perspective because refresh cycles moved from 30-40 months to 60-70 months. If you have 1000 computers, you needed to buy 200/year today, and would have needed 350 in 2005. Computers don't need to replaced as often, so slowdowns in momentum are very important because they indicate the institutions are slowing down purchases.

Microsoft is trying to push back on this by making it impossible to support Windows 10. We'll see how that goes.

When I was responsible for this at a large enterprise, I was buying 40k devices a year, every year. The Mac component was about 1,500/year. That dropped to 50 when the new keyboards came out and started failing. Losing a few hundred sales isn't a big deal, but some of that money that was going to MacBooks went elsewhere.

I have no data, and I personally use Linux and track point equipped machines, but my observation is Mac fans paying for their computers with their own money are not buying the new macs. I suspect that the sales number are reflecting corporate sales. I think Apple should remember that it is people from the former group who have managed to arm-twist corporations to look at non-Windows machines, that and the slow rise of Linux acceptance in more and more companies should make them listen to people who don't want Windows want.

I bought a Dell XPS rather than buy a new 13" MBP because of the keyboard issues + touchbar.

I had a touchbar 15" from work and once I left I bought the no touch bar 13" version. I was waiting for the 15" no touch bar version, but it looks like I'll stick with the 13" for now. Eventually they'll probably fix it somehow, but if not it sucks as I used to like both the machine and the OS.
