Well I haven't ever seen a laptop with 4:3 (1024x768?) although I loved my ancient 20" 1280x1024 5:4 monitor and there are lots of smaller 3:2 surface-like laptops. The 13.3" (and the tiny 12) still accounts for only 20% of the 2017 market, with 14.1-15.6 (and even larger) accounting for the remaining 30+50=80%.
This was about the market for Monitors though... not just displays in general so this e-ink display just doesn't cover a significant portion of the market outside of tablets or very small laptops. Typical monitor sizes are 19-34", with the smaller "totable" 15.6-17" sizes accounting for <20% of the market. 13-14" aren't even listed as monitor sizes by the marketing groups like IHS or Display Search.
Yes, I read the article. However, I have never seen a laptop use such a aspect ratio even in the olden days, and I'm not sure manufacturers would choose to now, because... These are high resolution low contrast reflective screens limited to 13" which do not hit the current market diaginal/area expectations for mainstream laptops, much less desktop monitors.
They are good for low power daylight operation and I'm sure there is a small market for people who don't like backlights and emissive displays. I like my kindle for books, but I also don't mind the backlight for indoor use. As desktop monitors they have missed everything but the smallest niche.
Good luck if you really want to use one regularly as the writer says,"Based on my research, particularly great e-ink monitor comparisons, these devices are not ready for professional, daily use. They are laggy, have staining/ghosting problems, and perhaps worst, are quite unreliable. It seems that the failure rate on both of these devices is quite high and user happiness is quite low. If e-ink is your only option (because of health reasons) then these might be a savior, but short of that it seems like your best best is to wait for future development in the space."
