Meh, I tried the Google Play Books Chrome app again, and it's still the same. You can't see or add highlights, notes, etc., while offline. And you still can't search in uploaded books, ever. Lame. Didn't bother to test reading position sync.

Well, the first company to offer highlight/notes sync in DRM-free books, between desktop, mobile, and e-ink reader, that's accessible while offline, wins my undying love - and my credit card number. Guess I won't hold my breath though. In the meantime I'll probably get a second-hand iPad mini... who knows, maybe it will grow on me.
