Most people don't need computer (full feature power, full power of choice) to solve their task, as could be seen with the smartphones, which are designed as appliances more or less.
I don't want most of consumer electronics to act like a computer, it is a deficiency for me.
I chose "dumb" Linux-based eBook reader instead of Android-based, because I want it to read books, full stop.
This quickly falls apart when you need to do stuff and be productive. Reading as a pass time is a different thing.
The problem is nobody makes this distinction for some reason. In my mind there's two types of software - the kind for doing things, and the kind for mostly consuming. As the wise Britney Spears once said, "there's only two types of people in the world: those that entertain, and the ones that observe"
It makes no sense for your CAD program you're building a company out from to be dumbed down.
Oh, this e-reader has lots of productivity features. You can highlight words (which are later stored in a separate folder), make bookmarks, easily translate words, use screen reader, etc.
I use it mostly for work and academic papers, not for amusement.
Most of the regular simple pdf viewers on the PC don't have this kind of productivity functionality in mind. They might have some, but in general they are not designed to work with read-only text.
