Either I came across a bad series or design is poor but the reading light is unusable. I am not speaking of ergonomics (software and hardware) disastrous, the navigation keys that give a feeling of hardware tinkering but especially beer screen quality and especially the pseudo backlight that makes harrowing reading. Sincerely, examine everything and this is not worth reading light that is some attention. We will console (a little) with the entry version with keys and screen do not exhibit the same defects; Nevertheless, the general ergonomics leaves very seriously inadequate.
