@L4700 Hi. Thx for testing. Frankly project happened just for me, because I have so many eReader but none was so light. Now I bought next Paper S3 device to my wife is my new tester :D. Future is unsure, for me - there's possibly all I need. And for others - there's slow feedback. What I am thinking about : HW improve - still trying to figure out some fancy Screen illumination fo this HW. Wifi portal for transfering books - USB disk mode is very slow, and removing SD card is akward. Sync readering with other readers (maybe Calibre, not sure now) Optimization (MCU is slow, but I see still some potencial. Secondly thinking about future porting to newer models - but it will need some donations to buy new HW. Until this time I have just one donate from my boss :D Sry for my English.
