My advice - don't get the Vox. It's not targeted to you. If you don't care about buying books from the Kobo Store, you can sideload non-ADE DRM'd books. It will do the reading part fine, but that reading's done in an app that runs on the Android platform which acts as the underlying OS, just as the Kobo Desktop application runs atop Windows.
You can have the Kobo Vox go into the Library by default when turned on if you activate the setting 'Start into the Library' in the Android settings menu. You can browse the bookshelf in the Library just fine.
I personally suggest you try it out in the bookstore before you buy it, as your post otherwise sounds like trolling for the sake of trolling if you come into a thread JUST to bash a device. Especially since this is your
SECOND POST EVER.
Or you could, y'know, just pick up a paper book and forget all the gadgetry. That works too.
And as a heads up, I can't think of any popular and easily obtainable reader which handles custom embedded fonts well. The PocketBook readers MIGHT, and I know if you use custom firmware the Sony T1 does... but most reader software won't. Aldiko, a third party Android reader, should be able to do so... but that'll involve more steps than you're willing to take with any reader. Perfect Viewer handles CBR fine, and without margins... but again, you're not interested in the steps it'll take to set it up.
