I will not argue with fan SONY. It is useless.
SONY Reader can and it is beautiful on a picture, but this device is not able elementary to show and format TXT-files. Not beautiful lBook Reader shows TXT, PDF, RTF, FB2, CHM, HTML, RSS, Wol. You can specify the menu in 16 languages. The device has opened SDK and all interested persons can write for it the software.
Now already the version of the device with WiFi is tested. In August sales lBook with Viziplex - the screen will begin.
