I initially used to have the 12.9 first gen iPad Pro but I never took it out of the house.
Then I upgraded to the iPad Pro 12.9 3rd gen thinking that I will surely carry it around. I tried and it was fine but soon started to be a uncomfortable.
Finally switched to 11" and I am totally satisfied. Can carry my iPad Pro and use the LTE data at public transport. It is just perfect.
When carrying the iPad out of the house you will have to factor in the carrying case as well which adds to the weight.
I believe Apple should release a 12" model which will be best.
