i just checked that walkbook and i'm not very excited about going to Turkey for a 328 Euro device... which looks kinda childish if you ask me... And i don't want to be offensive but Turkey is going to start a war with Northern Iraq... there are less lethal ways to get my hands on a e-reader device...
Although about the idea of a friend going to USA a buy one for me: isn't there a chance of damaged device and how could i return it then ... ?
---edit - after reading about the cybook gen3---
I have to admit the CYBGEN310BS doesn't look bad at all...
Are there cyrillic fonts for it? Major problems with it?... May be i should reconsider my decision...
