[Quoth]

The kindle and Kobo are best for reading novels. Poorer for other content and very poor for web content, interactive and photo/graphics.

You need a decent tablet, Nxtpaper or one of the other true matte paper-like screens.

I've Kindle and Kobo and had other eink. Kindle is actually a lot inferior to Kobo for managed metadata / library interface for the up to 18,000 novels (32 G). Almost no difference for reading.

Kobo is Japanese owned and based / designed in Canada. Images in epub don't zoom (and Amazon conversion of epub for Kindle reduces quality) because it was designed to read novels. Kobo has the kepub variation which does zoom, and you can easily convert, or even rename to have the image zooming.

But eink is best for novels.·
