Except...it isn't. Have you actually watched a 65 year old try and use the new content server - to browse a library and find interesting books to read, and then attempt to get them on a device like a kindle. Because I have, several of them, and it does not go well.
And it goes significantly worse than with the previous content server...they just find it much harder to browse around etc. The mobile first approach means all the controls (already obscure through use of icons) - get further lost into tiny corners on desktop monitors, and things like pages with infinite scroll (vs. easy to understand paging) - are not helpful to precisely that tech novice demographic.
Finding one book, if you know exactly what you want, is ok via search or author. But then the new browser reader further confuses them on the download side of things (and there already a bunch on in browser reading plugins (or inbuilt mechanisms) that do a much better job of the actual reading anyway).
(And the look of it in general - well, it's really straight out of the 90s...it looks like some of the pages on Halt and Catch Fire this season
)
