Lol, you are one of those rare individuals where I honestly never agree with anything you say, ever.
Nevertheless, think about your comment. If I am 6'5" and if I put the Surface at the same relative distance from me as a short person I WOULD NOT BE ABLE TO READ THE SCREEN. I said I'm tall, not that I have super-vision. Lol. Try putting your Surface 6 inches further away and tell me if you can still read the text.
Well if I did that I wouldn't be able to reach it. Kind of pointless on a touch device

How do you see all those jaggies without eagle eyes? Maybe pushing the screen a little further away is a solution to that as well. I guess you also just found a use for that 150% scaling option
All joking aside you should still be able to read the screen. I can stand above the Surface with the keyboard touching my waist (the width of the keyboard in front of me) and still make use of the screen. An adjustable kickstand would make little difference since at this angle I am looking nearly straight down and would have neck issues long before the screen not directly facing me became an issue.
You are in the very top percentile of the height distribution so it would not make sense to design for less than 1% of the users. I don't know how you can seriously expect a design just for your personal needs in that case. As a very tall person you should be accustomed to making special accommodations for such things and I don't know why the Surface should be any different than shoes, doors, car seats, etc. It may suck but I am sure being tall has its own advantages that make up for it. You seem to have found a very nice solution in a top notch adjustable angle case and that should be enough.
