Seriously, your 'proper' is utterly unavailable to me. I refuse to install Windows on my Mac just to run Sony's eBook Library software.
I fully appreaciate your situation and has nothing against, however,
I hadn't realised how much faster ePub was to open and change text size than LRF either, not having to recalculate the number of pages makes a huge difference, from 10 seconds to open to 1, from 22 seconds to change font size to around 6.
Makes it sound as if epub is a lot faster than lrf.
My point is that lrf is as fast or faster than epub. If you or anyone else refuse to use sony software, it is not Sony reader or LRF fault. They operate just fine. If for some reason it takes so long to open lrf vs. epub it is a user error.
