1) 15.6 inch laptop (14 is too small, especially with those bezels).
2) As thin of a bezel as possible (see XPS)
3) Camera on top! I don't want to show my fingers in conference calls. This may force the bezels to be larger on top, that's fine. (Pop-out camera?)
4) Offer the highest quality display from a color reproduction point of view, not the refresh rate. This is NOT a gaming laptop, or at least not a pro one.
5) The resolution should allow me to use the OS without scaling. If you can squeeze more than 1080p (1440?) the better. We need vertical space for coding! Some folks like 4K, so that should be an option.
6) Connectivity is important; lots of ports. Also, Intel WiFi cards, not Killer.
7) The sound should at least be decent. I don't understand how a phone can have better (ok, lounder) sound than a laptop.
8) Give us an option to optimize for power vs battery life. I want the fastest CPU (within reason) and a good GPU (1060 or 1050, but ideally 1060) at the expense of battery life, but others would like more battery.
9) I'm picky about the SSD that goes into the laptop. Either allow me to replace it or allow me to pick what I want (960 Pro).
10) Good trackpad, ideally with buttons.
11) Good keyboard, super important...
12) Under 6lbs
13) Cooling has to be top notch and the air intake cannot be on the bottom. I actually use the laptop on my lap.
14) Height should be around 1 inch. Making it super thin like MBPs is not worth the tradeoffs.
15) That logo needs to go or at a minimum don't make it glow...
