That depends on how you use it. If you're trying to split screen a MB12, then I fully agree, however multi touch gestures make rapid window swapping easy enough, and provide an alternative to split screening. For single task use on a 12" screen, I wouldn't give an edge to either OS. Also important is the robust file management and 3rd party app support that MacOS boasts.
Robust file management is definitely something the Mac has in spades over the iPad. However, hand me a 12" MacBook and tell me that I need to do a lot of file management tasks, I will eventually get tired of it being so small. For short bursts of productivity or watching video on an airline tray-table, I'll grant that it has utility. But as a daily driver? As a machine to get more than 5-10 minute sittings of work done? No thanks. Will happily take an iPad Pro over it any day of the week.
That's exactly what will happen IMO. It's been rumored that's what will happen and my money is on those rumors.
My timeline (only my opinion):
The 14" M1X will be released April~July 2021. The current 13" M1 2 port may be kept around until 2022 as a low tier option. I highly doubt the 13" will see another upgrade. Then in 2022 the 14" will come in a 2 port and 4 port variation.
Why does there even need to be BOTH a 2-port 14" AND a 4-port 14"? The reasons for there being both on the Intel 13" MacBook Pro side of things was directly related to power draw and thermal envelope differences between the two, and the reason for the 2-port 13" MacBook Pro having made the jump to Apple Silicon directly relates to the fact that the M1 doesn't seem to be able to provide more than two Thunderbolt ports or 16GB of RAM (features that are not an issue for the current Intel 4-port model). Once Apple closes the gap here, what's the need for an Air, a 2-port smaller sized Pro (13" or 14") and a 4-port smaller sized Pro (13" or 14")?
Hell, the performance gap between the Air and the 2-port 13" Pro is narrower than it has been since the Air split off into those two products.
I doubt they release a two port version of the 14 next year, but it's possible I guess.
The 16 will release same time as the 14. Prices will possibly be 100 dollars more than Intel counterparts due to new design.
Internals don't really concern me as whatever the release in 14 and 16 is gonna be rockin'. I'm just going to buy the lowest tier 16 with 16G Ram and 1TB HD. I'm hoping 16G Ram will be the base, but we all know that's not going to happen.
I do agree that the 14" will launch alongside the redesigned 16". I could picture 16GB being the minimum on the 16" machine and whatever higher-end machine replaces the current 4-port 13" MacBook Pro. I'm not the most sure about pricing. I feel like they'll keep it the same as before (despite the fact that their own SoCs will be cheaper than Intel's, give or take AMD's graphics as well.
I think Apple (and us, its customers) would be well-served with just 3 models:
MBA 13
MBP 13 (to be discontinued in favour of MBP 14 base model)
MBP 14, 2 ports
MBP 14, 4 ports
MBP 16
You list five models there. Even factoring in your parenthetical, that still leaves four. I agree that there ought to just be three models. Though, again, I'm still not sure why there needs to be a 2-port and a 4-port 14" MacBook Pro at that point. It would almost make more sense to further differentiate between the 2 models of 14" MacBook Pro (and maybe keep the 2-port version as a 13"), than it does to have a similar split as there was in the Intel era. Though, I feel like the 2-port 13" Pro could've just been renamed "MacBook" to make it more similar to the early Intel era version of the "MacBook" (in terms of being a good balance between the lighter Airs and the heftier and more performant Pros), though, I suppose the marketing opportunity to have "MacBook Pro" be one of the first migrated products to Apple Silicon, even if it was the weakest of the three Mac models that bear that name.
