I currently use a Kobo Aura HD with updated applications to avoid using the Kobo firmware and its associated silliness (e.g. a long refresh process on every power cycle to re-enumerate my entire collection into their sqlite db.) I have gone through a lot of different e-readers [1] but never a Kindle - the walled garden approach is not for me. This means that I buy ebooks in ePub form from Barnes&Noble, Kobo, Google Play, etc. or read converted pdfs of my former print books. In general, what I have looked for in an e-reader consists of the largest screen that I can afford (since pdfs don't scale well, IME), a micro sd slot to enable me to copy/sync books as I need it without being on the network, some basic functionality to save book markups, and maybe a web browser. [1] Some examples: Entourage eDGE (sic), Sony Libre, Sony Readers (PRS-500, PRS-505, PRS-300, etc.), Pocketbook 9.7", B&N Nook Simple Touch (still have it, running Android 2.x rooted). Edit1: more e-readers.
