Yeah, I like it hyphenated too, as I became very used to a perfectly straight right hand side after using LaTeX for a long time. And I want my ligatures back too
With regard to languages with long words, Dutch is a "nice" example. We stick everything together, so "computer programmer" becomes "computerprogrammeur", and "bicycle store owner" will become "fietsenwinkeleigenaar". Dutch eBooks often look... jumbled.... because of this. I don't expect the Kindle to actually have Dutch hyphenation rules. Heck, it doesn't even have a Dutch user interface.
But the problem will resolve itself, as many Dutch are so influenced by English that they spell words seperately, which in Dutch often changes their meaning, sometimes drastically so. It's actually called the English Disease.
