Conclusion: Both the Mini and Glo look and feel like quality eBook readers. Both have clear easy to read displays. The Glo has a very nice front-light that is more even than the Kindle Paperwhite (Note: I haven’t had the opportunity to try any Nook devices, so I can’t comment on how they compare to Kobo).
Pros: Mini is very portable, Glo has a very even front-light, Great battery life
Cons: Books tend to be more expensive and not available as early as Kindle / Nook versions, Mini version does not have a microSD card and requires a desktop app to copy books, No 3G capability
Excerpt: Kobo is betting that smaller is better. Unlike most E Ink readers, which have pretty much standardized on a 6-inch screen, the Kobo Mini has a 5-inch display, making this device all the more pocketable.
Conclusion: The Kobo Mini is the perfect blend of portability without sacrifice. It offers a feature rich experience for a very low price point. This would be perfect for guys who wear suits and want to carry it around in their jacket pocket. It also fits snug in any jeans or pants pockets, too.
Conclusion: The Kobo Glo gives you the impressive ability to read your ebooks in any environment. In the past you needed to be in an lighted area, and since e-Ink is not backlit like LED screens and thus prevented you from being able to read in the dark.
Conclusion: In the final analysis, though, we have to look at what we're getting for the money. Since the Kobo Mini costs about as much as similar 6-inch e-readers, you're not getting a discount for opting for the smaller 5-inch screen.
Pros: More pocketable than 6-inch e-readers like Amazon Kindle, Touch display, Sturdy and easy to hold, Superb font controls, Supports ePub, Incorporates reading metrics and awards
Cons: No audio features, screen lighting, or SD-card slot, Tapping near display margins is difficult, Small display means more page turns, Not much cheaper than some 6-inch readers
Summary: The affordable Kobo Mini is a likable touch-screen e-ink e-reader that's too small for some and not quite small enough for others.
Pros: The Kobo Mini is a modestly priced, very compact Wi-Fi-enabled e-ink e-reader with a 5-inch touch screen. It supports EPUB files, it's compatible with any e-book store that uses the Adobe DRM format, and with Wi-Fi off it gets up to a month's worth of battery life from a single charge.
Cons: Ideally, the device would be even smaller and thinner. Also, Kobo's selection of e-books lags behind Amazon's and Barnes & Noble's. Loading library loaners and third-party e-book purchases requires tethering to a PC.
Conclusion: The $80 Kobo Mini comes with a budget price tag yet doesn’t come off as cheap. Yes, to get to that price point there are sacrifices in quality — you won’t get the crispest screen or the fastest performance.
Pros: Light and comfortable, Size is good for small hands, Lots of control over text inside eBooks, Touch-controlled and easy to use, Access to eBook sources beyond Kobo's store
Cons: E Ink screen doesn't offer as much contrast as the competition, Could use faster performance
