I really like the mil-spec ruggedized laptops. I look down a row of those, and it really strikes me how they're all the same size, they're covered in ports (behind little gasket-protected doors), and they are so unapologetic about size and weight that they have sturdy carry handles attached.
So what I really want most is a standardized form factor. Then my concern is for the closely related concepts of power, cooling, and heat dissipation. My Third choice would be 1920x1080 display resolution or better. After that, battery life. If you're designing your laptop to be too thin and light to accommodate a standard TRS audio mini-jack, you're not designing for me.
The other thing lappie makers are doing is touch screens, which are just awkward on a laptop, and usually unusable in a docking station anyway. Never mind about turning the function key row into a touchscreen.
I care about weight. A lot. Because I travel.
People on HN like to say a particular laptop is "light enough." Sure, if that's all your carrying. But if you have a bag or briefcase full of other things like documents, every ounce counts.
Even classified documents can be shipped. There's really no reason I can imagine for anyone to be hand-carrying paper documents in the passenger compartment of an airplane in 2018, outside of a diplomatic pouch. And in that case, the laptop probably has to be disposable anyway.
Um, some of us still use (gasp) paper notebooks and pens. Imagine that! (I'll stop using them when you give me something with comparable power consumption and handwriting latency).
Besides that, in my bag you'll find a Fuji X100 camera, a Polaroid Snap, a (yes, paper) passport, a wallet, a couple of chargers, a cell phone, some pens, allergy pills, etc.
All of that has weight.
As for shipping - one point of bringing something on a plane is that you can use it on the plane.
Anyway, the point is - weight matters. There are things other than the laptop that a lot of people carry when traveling - be it personal or business travel.
