How to make an Amazon-free Kindle
(notes.ghed.in)
This is a most excellent place for technology news and articles.
My SO does, and it totally works.
That said, there are more options than Kindle. The Kobo eReader recently got a big revamp, and is now in many ways better than Kindle. And it works directly with library books (at least in the US, not sure about other countries).
So if you want an eReader, shop around first before jumping to the conclusion that you need to find workarounds for Kindle.
