This ereader was unveiled in Russia in April 2013, and it shipped in Europe in the middle of July. It was equipped with a frontlight and touchscreen on top of an 8" Triton E-ink screen (800 x 600 resolution). It also had Wifi, a microSD card slot, and it ran Pocketbook's own proprietary brand of Linux on an 800MHz CPU. The color screen supported 4096 shades ranging from a light gray to black (here's why).
Pocketbook has not offered an explanation for why they took this ereader off the market but I can add that they removed it in less time than they took to release it.
The Color Lux was on the market a mere 3 months before it ran out. And yes, it is OOS everywhere; I double checked and it doesn't seem to be available on any of Pocketbook's retail sites. Also, the product listing on Pocketbook's website says that it is unavailable.
Pocketbook has not offered any details about the number sold; just that it is out of stock. I wonder whether it will be back in stock at some point?
I would not be surprised if it isn't. I never put my hands on the Touch Lux but based on my experience with the Jetbook Color I would bet that readers found the color screen on this device disappointing. Thanks to the way this screen was built the color quality and resolution left a lot to be desired. The colors were faded at best, and the screen resolution was much lower than what could be achieved on a 7" Android tablet.
I am also not sure there were very many people who bought one; it was set to sell in Russia for 9990 rubles (about $310USD). Needless to say, I think an Android tablet is a better value.
