The Daylight tablet is the closest to Playdate display among the tablets listed in the article.
The play date screen is beautiful. So is the daylight computer but no colour is just a deal breaker for me unfortunately.
Some charts/diagrams use colours and being unable to understand how the colour is being used is probably going to end up being too annoying in the end for my intended usage even tho I am predominantly looking to read (pdfs and blogs)
For books I still prefer the real thing whenever possible

It seems that they took a certain Sharp screen and simply took off the colour layer. Citation needed.
