Yes, that's the drawback of PDF ebooks
And if you want it to be "perfect", you have to avoid widows and orphans, which I think I saw somewhere. In my PDFs, I chose to set \widowpenalty and \clubpenalty to 10000, and add some stretchability to \baselineskip; this results in no widows or orphans, but the lines are a bit spread out sometimes (it's not as bad as in printed books, because you see only a single page at a time, and you don't see the backpage either)
