On the face of it there seems to be a lot of choice around for epub reader software for Android until you realise most / all of the above are unable to read Adobe DRM epub which is nominally still the standard.
Not a deal breaker for many on mobileread who prefer to strip the DRM but sometimes I do not have the time or can be bothered to strip the DRM and would happily just want to read a DRM epub on my Android phone.
So I suggest an update on the above list to clearly state which software can read what type of DRM epub (if any) would be useful.
It really surprises me that Adobe or A.N. Other big player who has adopted Adobe DRM epub e.g. Sony haven't put some resources into developing a software reader for Adobe DRM for use on Android / Windows / iphone. It is Amazon's strategy that I thought played well to the galleries. Being able to synchronize between your phone and dedicated ereader is functionality I want and I would guess is popular?
