Flipping back and forth in an eBook is not a reader-friendly experience, in my view. I'm not really fan of doing it with a regular paperback book, but the eBook just doesn't lend itself well to doing so.
I don't ever plan to use a dictionary. For my style, I make sure everything is either understood by context, or well-informed in the narrative/dialogue (without obvious info-dumping).

Leaving some mystery to the made up words & terms, defining them partially by context, can add an air of mystery to your tale.
Actually, I'm not against glossaries. They do add an extra option of convenience, plus the clout of reminding the reader just how much stuff you have. (Or with an organized magic system like Mistborn, it's Just Kewl.)
But I think they shouldn't be a crutch. There's a continuum between maximizing the drama of a few terms and carelessly swapping in words on the grounds that "That's how they talk, and the reader Can Use the glossary," ignoring that flipping back and forth is hard to justify as exciting reading behavior. (And e-reader limits matter!) But new words do make a good writing focus, a priority on what to dramatize in a scene. "Could this work without a glossary" makes writing better, but I wouldn't say just not to use one.
(Of course, I just don't write thousand-page epics. But even there, that has more to do with whether a word can use help being remembered later than how casually you can throw it in.)
Now I'm with you
A glossary is for the words/concepts you can't explain any other way. Not an excuse for lazy writing.
Or, at the risk of re-using the classic, a glossary is Telling, not Showing. Doesn't mean it can't reinforce the real work on presenting a word (or I guess some minor phrases that can only be explained there are still worth having), but don't let it be your copout.
