Engadget: While tablet and smartphone manufacturers battled it out over screen sizes, e-reader makers seem to have settled on an industry standard of 6-inch displays. It's a trend that Kobo, at least, is trying to buck. The company is supplementing its flagship device with a smaller model, the $79 Kobo Mini, which has a more diminutive 5-inch screen, and weighs less, to boot.
TechRadar: If you'd rather not travel with a high-end tablet and think that even a Kindle is too big to carry on the daily commute, the touchscreen Kobo Mini could be the e-reader for you.
At a mere five inches across the diagonal, it's the tiniest e-reader we've seen since the Sony Reader Digital Book PRS-300, though it's not the slimmest.
