I've been using e-readers since the first Kindle came out. The are totally worth when the docs/books you read fit properly in the screen. They are normally around 6 inches (there are newer brands with bigger screens) so pdf's won't fit and you'll need to scroll both ways which sucks. There are tools like https://www.willus.com/k2pdfopt/ https://www.willus.com/k2pdfopt/ that can format pdf documents for Kindle size. It's pretty good. Anyway, I would say if you can get your books or documents on epub or mobi or amazon's format, then e-readers are a great option. I personally use the Oasis and the battery life and screen performance are awesome. I think the screen size is also a bit bigger than the previous versions.
