In this case, it's not the weight that counts. At least for me, the difference between the size of 15" and 12" decides whether it's comfortable to use in an airplane or train seat. The size also has a lot to do with whether the computer fits in a bag. I could cart the 12" in a hip bag or messenger bag, the 15" I would not carry other than in a backpack.
I do recognize that laptop size is a very personal thing. One friend of mine who is close to 2m tall, always carries a hip bag large enough to fit the 15" anyway, and he is really too big to open a laptop while seated in a transport. Obviously smaller size wouldn't matter to him.
If 15" screen is irresistible, where does that place 20"...
1280 * 854 = 1093120
1680 * 1080 = 1814400
1024 * 768 = 786432
1814400 + 786432 = 2600832
The 12" + 20" solution gives you 2.4 times the space
