30% cheaper than the Amazon competitor, he draws on a vast pool of e-books. And thanks to the support of the Telekom of all public wi-fi access for free (we did not tried it yet). At Amazon you pay it neatly with the 3G models!
It is important that it is fun. And there is no question. The Umblätterzeiten are faster than that of a real book, the illumination graded very even and very well with the light (from very light to almost dark).
Even PDFs are shown quickly. And through large PDF files with images (I had a free on buildings available for testing) can be moved well with the fingers. Of course, one must the representation of such a document does not compare with that of a tablet PC, but what the readability even in bright sunlight more wins.
The "screen" is good anti-reflective coating to keep the device easily in one hand, which you should choose the right because it turns the pages with one touch of the right edge of the screen.
Conclusion: Highly recommended!
Besides, he has other tests better than the Kindle ;-)
