No, you are not alone - I am second user of this fine piece of tech. And still astonished by the solutions implemented into it and it's ease of use

.
I am wondering - why this type of tablet with monochromatic, no backlight screen didn't catchup? Is so similar to e-paper!
Maybe like Great Eastern - it was before it's time?

Like Sony Tablet P - foldable tablet also from beginning of 2010's (also am a proud owner ;-)).
Thanks for the resources - will go through them.
Mine I bought some 3 years ago secondhand - with some apps already installed. But looking forward - if I can find something new

.
It laid in cupboard for way too long. The artificial leather of case was falling apart - only now I have devised a new case - from new old stock of Sony Xperia Talet S case - yellow one; they are nearly the same dimensions - so only some tweaking and some double tape to secure it was needed :P.
So now I am reviving it.
And greeting from Poland
