Amazon should rather support epub format if they care to have some success in Europe and maybe some other non-US markets.

ePub is not the problem. It is the Adobe DRM that is comes baked into most ePub documents that are sold.

Which (I'm very sad to see, but maybe it'll change in time) Google has adopted :\

I'm not so much. My sony reader is compatible with Adobe DRM. :)
