oh ya, there's work-arounds... but it's just funny that they FINALLY started implementing this limitaion.
as for "cheating" the system - i'd hardly call eagerly paying for books cheating anything except an antiquated distribution model that prevents digital books from being sold in any format in a given country.
it's these distribution deals that predate the internet that are creating the issue in the first place...
if i really wanted to cheat i'd just download the book for free, strip the drm and put it on any device i choose. see, i'm trying to play fair!
