Kindle vs Kobo

Every few years I buy ebook reading devices to get a feel for where things are going. Not much news here really, things seem to have stabilized a lot in terms of formatting, price, and reading experience. They don’t compete on much, now that things have settled a little. So I won’t comment on it much,  just to say that the Kobo Aura wins for me over the Kindle Paperwhite, purely on the basis that the Kindle displays advertisements on the screen when in sleep mode, while the Kobo displays the cover of the book I’m currently reading. It makes a huge difference as to how I feel about the device.
