Why the Icarus gets bad reviews, I do not quite understand. Property me this device specially because my Skoobe Subscription zuelegt. Since I am in possession of Kindle's and a Kindle Paperwhite's, the comparisons are of course not deny. The biggest advantage of the Icarus: He has the open operating system. Having expanded the software voristalliert with a system update, I can now, after some months, the App Store, sponsored by Icarus, use. Previously, you had to the somewhat cumbersome install apps (.apk as files). For me, a great new feature. I like also the side buttons for turning and for the refresh of the page, if you want to be ghosting effect disappear. At the contrast could not be filed, however, which of course is also app-dependent. The internal reader looks good, but is not used by me, because I read exclusively with Skoobe. The shelf life of the battery is in my opinion really great. I come with a charge for several days to weeks out with a non-permanent use, but then with medium lighting. My Icarus also has only a slight cloud formation at the bottom, which does not bother me, because there is in the Skoobe app a dark bar. (Because I have to change the Paperwhite 5x, disaster). All in all, I really recommend the Illumina, who is tired to read on your smartphone or tablet. who loves exclusively Kindle books should remain with the Kindle. But I am sure that the Icarus will give an even more convincing result after a few updates as already.
