"non commercial" sources are bad for the publishers but they will boost device sales.
when someone buys an iPod and Apple says that you can put 10 thousand songs on it, do you think the guy will buy those songs for one dollar each?

Same thing here
Personally I'm OK with compensating the authors but I'd rather not have 90% of the money going to publishers.
Also, please allow me to suggest the
http://search.digitalreading.net site where you can search for ebook "warez".
The site uses Google CustomSearch which basically means that it uses google search but limited to a list of websites only.
You can sign up as a contributor and add sites to the list.
I've currently added piratebay and rapdishares, they're good sources for torrents, you're welcome to add more.
Sic.
