I firmly believe that it's downright impossible to give a great experience with the same UI using touch/keyboard+mouse. You're just bound to have ugly tradeoffs in usability xor visuals.
It also seems to me like an ergonomic nightmare. I'm curious to hear if people who use their iPads like laptops (with a keyboard and trackpad) feel like they want to reach for the screen. I'd imagine it's a last resort.
I often use an iPad in a keyboard case and I have a BT mouse. I constantly switch control methods depending on the situation. Sometimes you want precision and use the keyboard or mouse. Other times you want more interaction and will use the touch screen. Scrolling is often easier using touch. If I had a touchpad, the mix might shift a little but not drastically. I also like to switch up controls as a hedge against RSI.
Touch is not an ergonomic nightmare and it is not the last resort. It’s just an option where appropriate.
