The new Kobo Aura HD reader is positioned as a premium e-ink reader. The manufacturer goes so far as calling it the Porsche of e-ink readers. According to the reviewers, this claim is largely met.
Rather than attempting to undercut Amazon on price, Kobo chose to provide deluxe features. The display is a large 6.8" screen and it features a 265 dpi display. At 1440 x 1080, it is the classic aspect ratio of 4:3. Before buying, check out the pricing and availability of books that you like. Some reviewers commented that Kobo's store has higher prices and a smaller selection than Amazon's selection.
The Good: Larger size, high resolution display; ergonomic details and build quality; supports EPUB format and Adobe DRM.
The Bad: More expensive than Kindle's e-ink readers; e-ink is not competitive with a tablet display and it is not good as a general purpose web browser; Kobo's store may not have some titles that you want.
