Hi! What screen size are you rocking on your laptop and how do you feel it has effect on your productivity. I'm myself right now using old Thinkpad w540 with 15 inch screen and I feel it is sweet spot, maybe I could get more out of bigger 17 inch screen, but with cost of even more extra weight. Old w540 can be a struggle to carry around but trusty.
Other way I almost always feel crammed with 13-14 inch screen laptops. Form factor is nice for the laptop tho. And is good for office work, apart from screen scaling on windows, but more advange work like 3D modeling architecture Revit with heavy space taking Ui in software leaves very little actual working are / 3D view.
What is your take on this subject!
