Yeah, I suppose they could also be useful for translation when travelling someplace where you can’t read the language, provided it’s reasonably accurate and not too laggy?

In terms of occasional use, I was thinking they could be good for loading speeches or music/lyrics when you’re up on a stage. But while that seems like it ought to be a fairly trivial feature to implement, as both a software developer and performer, I could see this being more challenging than you think to get a good experience out of that sort of app.
