Dale's point about a limited processing capacity is what I was trying to demonstrate as a general observation - the current eReader devices have limited computing resources relative to the needs of a "proper" pagination, so some compromises have to be made.
Sony may limit font type/size choices and compute pages for them. Cybook took a different route of more font type/size flexibility but less accurate pages.
Thus the conclusion is that better pagination has to wait for more powerful processors combined with batteries that can support them. I think Cybook is in a good shape as its battery is more than sufficient so they could certainly put Cybook CPU to work more with a the next software update. The suggestion of a background pagination based on the current settings and storing results in its data files associated with an eBook would work well. We only use a small number of font type/size combos for any particular book. Based on my current experience regarding battery life, I would not loose anything if CPU did more pagination work and used more power. I still haven't managed to drop below 50% so the current battery has more then enough juice.
Again, the bottom line is we'll need some patience and understanding as this discussion has demonstrated that while on the surface it seems simple, actually it rather difficult problem to solve.
BTW nice ideas/info being posted, great stuff
