If it is plagued by problems, this flagship will become a major iceberg.
It's a Mac, I really doubt the new machines will be plagued by problems
I've used Macs since 1988, and PCs for about as long (assuredly, using Windows PCs wasn't enjoyable until Windows 7). Current Windows hardware offerings and Windows 10 are quite enjoyable (though sometimes hit with driver issues when a new gen architecture hit, as when Skylake first shipped). I review them all, respect what the various companies are doing (or try to do). It's good to see innovation, as someone with a very long Mac background, I'd like to see Apple continue to drive useful innovation and not fall prey to their own cult of thinness and dubious touch screen replacements (as their execs described the Touch Bar, minus the "dubious" of course).
