Whether HUD makes or does not make any sense is really up to discussion, I like pieces of the HUD and I think it can be great for my laptop (12''). That's a bit irrelevant though, since Unity does not work, has tons of bugs and you can't change anything (well, you can, but then you just expose more bugs). Also, even if the HUD were useful, it's responsivness is so sub-par, that's impossible to use. I for one don't have patience to wait after keystroke and before starting typing. It's an absolute engineering disaster and this is what is the real problem.
