jgray,
How old is MS Reader? What is its current version number? Sounds it is a lot more mature than Cybook's software, so I am not surprised it works better.
Both PDA and eReaders use similar processor types. However, PDA have been moving to more capable/powerful CPUs as their software evolved to ever bigger more powerful versions. Also, they don't care much about battery life so tend to use more power. Therefore it is not surprising that MS Reader being much more mature and having more resources would do a better job.
Cybook on the other hand is using Linux where more emhpasis is placed on power management. In general, the entire design approach and expectations are that eReader spends most of its time being idle (obviously) so processing is limited to bursts of activity, like page changes and menu access. So you wouldn't necessarily spawn a bunch of background threads for pagination. At this point I am guessing too much ....
Based on the current experience of a very long battery life on a single charge it is reasonable to assumbe that Cybook CPU is not very busy. Perhaps Bookeen engineers will change their approach to pagination in the future and make more use of the CPU.
Point taken. It works in MS Reader. I will also remind you that virtually all portable computers based on Microsoft software never get a very good battery life. On the contrary, laptop batteries are famous for lasting mere few years before they no longer can hold their charge. Therefore it is perfectly valid to consider a different compromise: less features and longer battery life
