I am largely with you in this camp. Many laptops almost get there. Lenovo looks the most promising of the major brands, and there are more and more OLED laptops coming out which is really nice. Razer also seems plausible but I am concerned with heat issues.

Dell unfortunately does not do fn-arrows for some incomprehensible reason. I worked around it with an AHK script for win-arrows but the fingering is worse.
