I had only had X-Series laptops before and I cannot tell. The haptic feedback on the track pad is emulating the buttons reasonably well, but, yes, I am missing the buttons! It is much more tiring on my fingers than using the external trackpoint keyboard. Particularly the middle mouse is harder to hit. I can reasonably live with the usb-c as there are great small USBC hubs. I actually started to enjoy that I can connect eanythingbon either side. For cooling: the non-coated case material and particularly having the air flowing inside the display joint ( I think like Mac books) makes a difference IMHO.
