My wife had received a kindle gift and I was jealous especially in summer camping where she could read in for 2 weeks without recharging (and which avoids lugging a suitcase of books that quickly deteriorate during the trip) ; playback is facilitated VO: English reading very easy as pressing a word dictionary English French (or English) opens. the KOBO has the same advantages; After comparison I chose Kobo for flexible file formats that can be played. AURA also has the advantage of backlight which can read at night without turning on the light (and therefore without disturbing his partner / companion) but then the battery will discharge a little faster (remember to disconnect the wifi also save battery). Kobo is Lighter and thinner than the kindle (old model?) ebook files are read (only the page numbers are not always in the same place and "eat" often the last letter of the word). to improve; English French Dictionary; should be the definition of words in some idioms, leave a little longer the book cover to the opening that one records the name of the author !!!. + using Calibre software that removes the DRM we just convert Kindle epub files and vice versa; a bit laborious but possible to have both types of reading lights.
