ePub files conform to a common standard, but companies vary the Digital Rights Management layer that they wrap around them.

We were getting to a reasonably clear situation where everyone using ePub who wanted to add DRM was applying Adobe's ADEPT version, but over the last year it's got more confused with B&N and Apple applying their own variants to lock people into their own stores.

The ePub format itself should work on any ePub device if you have the rights to the file, but as with any standard there are files that deviate from it in some areas, and the standard itself is evolving. The issues with conflicting DRM schemes vastly outweigh issues with deviations in the underlying ePub file.
