My thoughts exactly when I first heard about ePub. It seems like there is an aweful amount of time spent on schemantics whereas really the main content is just XHTML 1.1.
If you take a closer look you'll see there is more about it. First, ePub has to be supported by a wide range of hardware. That includes old E Ink devices with limited memory and slow CPU. You need to do something about the XHTML file and included static material so that it won't overflow your device's memory. Second, there is the question how to include and present various metadata, how to include inline images, support DRM (some people ask for it...), extend functionality through XML, and support audio/video content.
