It sound like what you need is a 360 laptop which gives a good option when folded back but acts like a clamshell most of the time
I am always surprised when people say solve a problem not being asked be it laptops or phones. Why anyone would think one format suits all is beyond me
I watched my kids grow up with clamshells and they just sit or relax differently and would of got far more use out of formats now available today.
Same as my wife and her liking for light weight portables she would be completely frustrated with a 2 in 1 or anything over 1kg clamshell.
It's a big thumbs up in my book for MS inspiring so many options on formats and a big thumbs down on Apple for not
It's good to have choices and variants that morph, evolve and inspire and not just give 1 format with colour variants to match your lounge or kitchen then gouge you on accessories
