Anecdotally, I tried OG Surface Pro back when it launched. On my lap the kickstand was extremely unstable; on high speed rail chairs the angle of kickstand was extremely steep and uncomfortable; on university desks and cafeteria tables it was okay but never good; only on airplane couches and Starbucks tables, which I’m not as privileged to say I use with frequency, it fit, at all.
The kickstand has reportedly improved since, but the problem is that it’s a highly engineered design for multiple but precisely pre-determined situations, with a limited adaptability.
Traditional laptop hinges on the other hand, oh they work beautifully between 0 to 1.1g under any posture, if you could put it on a lap or table it’ll be nice. That’s it. Way better than the kickstand.
