But the problem if someone needs a laptop is:
-M1 ULTRA isn't inside.
-They could buy the M1 MAX
-But they need to wait every time 2 years = 10 years in total for M6 MAX, until they will get the performance of the M1 ULTRA.
-Why should someone wait 10 years if they can buy directly a laptop with i9-13980HX + RTX 4090?
How many "someones" is that?
The mobile RTX 4090 is really an underclocked 4080. The market selling into is the fringe of the fringe where Nvidia blowing smoking up their butts labeling it a 4090 ( when it isn't) is 'just fine'. About as much 'lust' factor selling these system as anything sensible from normal laptop metrics. Apple really isn't out to sell everything to everybody.
These 18" ( mostly plastic body ) laptops you have linked in a flurry really are not going to do as well as aircraft grade aluminum chassis when it comes to portability. Apple's solution will be heavier than these. As others have pointed out there are caps on battery size if portability is suppose to span riding in an airplane. So operating lifetime is sagging.
At some point of sagging battery life and 8-10 lbs of laptop the 8 lbs studio is about just as luggable if only going to use it on a 'plugged in' desktop location after transport. ( is there is a display docking station at either end of the desktop-to-desktop journey then the keyboard , mouse , monitor doesn't really 'have to' move for a substantive number of people. )
The other major flaw here is the concept of "Apple has to sell it to me , right now or it is a fail.". If Apple doesn't sell to certain people now , but sells to more folks in the future ... that is just fine. Short term it isn't like they are broke and can barely pay the bills. Incrementally, growing the Mac product line into future areas they don't tap now is not a 'bad thing' . Apple doesn't have to have exactly the same set of customers in 2024 as they did in 2009.
Usually there is a flurry of "but there will be a 6090/7090/8090 in the future ... blah blah. What matters more is what user's workloads are. There is a narrowing subset of users for which moving to those future jumps will be enitrely. However, there will be another sizable subset for which it does not.
There are still more folks on the planet that do not have a classic PC (laptop or desktop) than do. The group of max lustful tech fanatics that churn their laptops chasing the latest shiny "max power consuming laptop GPU" is relatively stagnant. It isn't a high growth market. They are sales, but it isn't moving in an expansive way.
Odds are pretty low that Apple is going to do a "luggable , desktop placement" laptop anytime in the future. Stuff bigger and heavier than the old legacy MBP 17" .... probably not. An more affordable, lightweight 15" model will likely sell an order of magnitude more units per year with zero tweaks to the SoC design constraints the other laptops are using.
