Got the OH a Kindle for Christmas. It’s a seriously impressive bit of kit.
Contrary to popular belief ^^ you’re not tied to Amazon. She’s dumped PDFs for work on there, and I’ve converted a bunch of ePub stuff to the Kindle’s .mobi format without issue – used a free bit of software called Calibre which is basically iTunes for books.
Stuff you buy from Amazon is DRM’ed so you can’t copy it, but I believe there’s ways round that. I’ve not had cause to explore this yet though.
The thing syncs with Amazon so if you install the Kindle software on your PC or phone, when you move between devices it remembers what page you were on and suchlike.
Also does audiobooks. Battery life is extraordinary (I bought it three months ago, opened the box on Chrimble morning and the screen was running a screensaver; I think it only uses charge when the display changes, so it can hold a static image indefinitely). Readability is superb, you can view the screen from silly angles without issue. It’s thin and light, weighs less than a paperback book.
Can’t recommend it highly enough, if you want an ebook reader it’s the wasp’s nipples.
