I believe you have an error in PWM dimming screen section, the values on the scope are in kHz (kilo-hertz), 1000x higher than reported in the article. Also, in one photo the marker was erroneously positioned to include 2 periods (T) instead of single one.

I once had an opportunity to look at a 60% sRGB IPS screen on acer laptop. It felt like looking at a screen limited to maximum 256 colours, as if painted with pencils. My chinese budget laptop has a by far much pleasant to the eye IPS panel.

Not good enough, this screen is unacceptable.
It is not only people that edits photos that needs 100%sRGB. It is bad for eyes to have a panel with so low difference in tonality, plus everyone sees a video in a laptop.

It is my opinion that laptops are in peril due to this commercial behavior: TV, PC monitors. Tablets, smartphones all have much better screens than laptops. So people move to other alternatives.
 

Well, there you go - "good enough" for >%90 of users right out of the box. :)

While there was a time when small & lightweight required a premium over the similarly outfitted larger 15.6" & 17" models which surely MIGHT still be the case here with a $700 asking price for an 'basic' system that ought to cost in the $300-500 range.

Sure, as many folks have moved much if not most of their 'home & personal' IT needs to their smart phone of choice, there will always be use patterns where a Laptop fits better and is easier to use then a phone or tablet.

Given this until will be transported mostly in a backpack or dedicated sleeve or case, the plastic construction reduces its weight as a full metal chassis is likely unneeded at this price point and usage class.
