Oops. Sorry for my prior cavalier comment generically excluding tablets and smartphones. I hereby generically unexclude them (waving magic wand with a flourish...). I do use iOS Reader Applications for USB connection to iOS devices. And Calibre Companion for wireless connection to Android device.
In fact, upon further consideration, I hereby unexclude from the list all devices ever made in past or future, any brand, any size, any weight, any capability, any reader apps, that were ever excluded, potentially excluded, never excluded, or impugned in any way.
Note the Pocketbook, which hadn't been excluded, but nonetheless sadly ignored.
I hereby attribute the content contributions contained in this post, that were gleaned from other posts, each to its original contributing post and poster (waving magic wand, woosh.)
Regarding using out-of-the-box with calibre, consult this:
