Though if it's as simple as that, the Glo HD is looking more appealing to me again.

That's what Jon is saying, but he isn't completely right. Changing the extension will do what Jon says, but the reading position and bookmarks won't work correctly.
In a kepub, each sentence is wrapped in a span. This has an id. The location system uses these ids. If you just change the extension, when you close and reopen a book, you will always be taken to the start of the chapter you were up to. And any annotations stored will not be redisplayed in the book. The plugins add the spans to the epubs. The plugin also adds some extra divs and CSS that the kepub ereader expects and helps with the way it does the formatting.
Note that the kepub is still a valid epub. If you opened it with any other epub reader it would be OK.
