I would have been interested in the Switch Lite if the ergonomy had been improved. I have big hands and the original Switch is almost unplayable for me in handheld mode without my Satisfye grip (which was pretty expensive). I think shooters like Splatoon are unplayable in general because of the placement of the right stick.
I expected Nintendo to improve this in a revision without detachable joycons because it is not restricted by the docking function and you can still make it compact. The fact that the controls almost look the same as on the original Switch tells me that they don't see any problem with ergonomy at all (not surprisingly, as almost all Nintendo handhelds after the Gameboy Advance were unergonomic).
