Well, it is possible to buy M92 in Czech Rep..

But it seems, that it is some kind of ArtaTech reseller... The booklet is said to be in Polish.
I bought mine last year in a Dutch e-shop
www.ebookreaderdiscounter.com. It was quite expensive, but I wanted it right then (it was a Christmas present), and did not want to wait...
I understand that ArtaTech has to protect licenced SW like TTS, but I personaly prefer "open solution". I use M92 for reading and do not need TTS, but for blind people or small kids or for learning a foreign language it might be of great value...
Regarding the cover. The standard one is not the leather one, but it works just fine. My M92 fell 2 meters (switched off and in closed cover), last week, and no harm! I cannot imagine using e-book reader without a cover.
It is clear that M92 is nice piece of hardware, quite well designed and manufactured.
Its weak point is the firmware and mainly the interface. I and probably most of users would prefer improvements in the workflow of working with documents (faster acces to tools, etc., multitasking and as less bugs as possible). TTS, cloud, ... are of less importance to my opinion.
