Pros
Cons
It's not just the limited sharing or printing capabilities which are bad. The worst thing is you can't read the books properly in a real full screen format, or rotate them. The program's user interface looks like something out of the mid nineties and is cumbersome to use. Overall the reading experience is abysmal. Too bad if you have to spend hours in front of it, damaging your eyesight , because you have no alternative.
There are so many formats and readers around, who on EARTH would want to restrict themselves to something with such limited capability for sharing and exchanging between formats? Bought a hardcopy book that came with a free vbk version - it's going to be very lonely. Get with the century guys.
