As I know, you have an EE. So, I think your device doesn't need this development feature at all

I thought it would be rather useful for people with PE, And the main goal, as I could presume is to open big PDFs. Maybe, to read books, but that's not for me, I like to read it on one type of screens (either E-ink or LCD). But PDF - yes, it a real problem.
+ to surf internet.
So, I think, that is.

maybe, it could be easier to build an app for this two goals, what do you think?
