What I miss about tablets is a good case to turn them into a real laptop. I think the kickstand is fine if you want to use tablet mode, but I think it sucks for your lap. It really doesn’t work as well as a normal one laptop.
What I would be very interested in is a keyboard deck accessory like the Surface Book 2, but without any hardware (except maybe a battery as an extra battery and to balance the weight).
The handy thing about Surface tablets is that it works much better for multi-monitor use than a Samsung tablet. Android and even DeX is just not up to par with Windows for multimonitor desktop use. And it’s so annoying that Samsung is the only option (or Apple), because everything else doesn’t support video out over USB. Let alone that they offer Thunderbolt/USB4 for docks.
Surface products work very well with applications for notes. Like OneNote. If you need that, a Surface is a good solution. Personally, I would buy a Rennaiser pen (it’s more pleasant in my opinion).
If you don’t take notes, just buy a laptop. Surface products are then really superfluous. And I would still recommend a Wacom product to draftsmen.
