Re: Ave Kindle, te morituri salutant
"I read a lot on my Nexus 7,but only when my Kindle is charging or, more frequently, if the book is an epub that requires using Aldiko rather than Kindle. "
Mostly I use Calibre to solve that problem, and organise the collections on my Kindle. [ http://calibre-ebook.com/ ]
It is .pdf that requires the Transformer to read comfortably.
