1) a touchpad with physical buttons - those single pads are annoying as hell to use for longer than 10 minutes
2) Thermals staying 45 or less, I've never had good luck with lifespan of any laptop that gets hot, cause they only get worse with age
3) In-home warranty option, I don't care too much about serviceability since I always get in-home warranty. So their problem, not mine. Only exception is soldered HD, that is a big no. I can tolerate soldered ram if they give good options on the cheap.(min 32gb)
4) Good keyboard, I hate tiny arrow keys, especially for left and right key, even more so when they put page up and page down there and I always misclick. And keyboard should have good travel, I don't want my fingers to hurt. Preferably there are dedicated end key, lots of remote desktop use ctrl+alt+end.
5) Removable battery, cause the heat will kill the battery
6) 100% srgb screen, IPS - for when I do graphics
7) USB-C charging
8) At lease 10 hour battery life
9) A video out, don't care which be it vga, hdmi, display port, usb-c or w\e
10) Linux support, I don't care if they offer it on their site, I just prefer that it works
