Kovid must be excited - another liseuse file format to reverse engineer

the Intermediate File Format (BVD) - at least you can backup your BVD files, or so it said.
Only Brother can make a liseuse manual look like it's actually for a typewriter or something..
Heavier than other liseuses on the market, and shorter battery life to boot?
Strange that it's limited to max. 2 GB microSD cards.
4 shades of grey? Not exactly competing with the latest liseuses! My PRS-500 is limited to 4 shades of grey too! - Makes me wonder how fast their screen refresh rate will be!
Seems to have a heavy reliance on security to sell it to business. I suppose if I wanted to carry around secure documents to read it would be useful - but whats to stop someone looking over your shoulder once you've opened and are reading the encrypted document?
