That certainly is a possibility, but IMHO, Apple long ago decided the whole world wants everything to exist on screens that are no more than 1/4" thick and 10" on diagonal -- and seriously, keyboards and mice are so 1980.
......
Certainly there are many things humans want to do that work well with such a format. There might even be some mini-DAW cases where that is a good thing. But I do not believe that anybody in any position of authority at Apple appreciates that there are some applications that really do work best with big, powerful desktop platforms and lots of glass.
You've not yet seen a 27" 5K Retina iMac yet then? Or even the 4K that's been around for quite a while? Or noticed you can hook up additional screens to any Mac apart possibly from the socket-light MacBook.
The iMac Pro that's been announced as launching in December looks interesting as well. Probably cost a fortune though. It will be interesting to see if the very long in the tooth and very expensive "wastebin" style Mac Pro is the last of a separate "Pro" line from the iMacs.
Incidentally, a high-quality 10" or thereabouts screen built into a very portable tablet is pretty good for lots of the "everyday" computing stuff most people use computers for. Apple got into the tablet market early and have captured a pretty big chunk of it. Portable computers - even phone sized portable computers - are very much where a lot of the market is these days. MS were slow into that market, possibly because they don't sell hardware as the major part of their business model, and are playing catch-up in many ways. Interestingly, the MS decision to make desktop Windows 8 onwards look and behave like an overgrown very easy to use tablet with the "traditional desktop" functions playing second fiddle to the wonders of screen-filling menu tiles and "apps" isn't a route Apple decided to go down, MacOS is very much still a desktop Unix (well, FreeBSD) based OS.
I wouldn't write Apple off yet. Nor MS for that matter. Both systems have strengths and weaknesses.
