This ereader is licensed from the same OEM as Trekstor's other ereaders, but as you may have noticed, the Pyrus 2 LED doesn't have the "Digital Ink" knockoff E-ink screen found on its 4.3", 8", and 6" siblings. Instead this ereader has a real E-ink screen.
The shift from one screen supplier to another is likely due to the frontlight. E-ink is capable of attaching a frontlight to their screen and selling the assembly to ereader makers, but they're not all that interested in simply selling the frontlight component. And apparently the OEM who designed and built the Pyrus 2 for Trekstor can't yet make their own frontlight.
The Pyrus 2 LED is a basic ereader, and its eBook format support includes Epub, FB2, PDB, and PDF. The Pyrus 2 can also read html, rtf, and txt files and display BMP, GIF, JPEG, PNG, and TIFF image files.
There's no information yet on battery life or weight, but I do know that the Pyrus 2 LED will officially debut in October at IFA-Berlin.
This is going to be a rather curious product at its price point. It's going to cost 80 euros, or about 10 euros more than the Trekstor's other 6" ereader. It's not the cheapest ereader on the German market, but it is the cheapest one with a frontlight. I think I can see the appeal.
