Anyone using the CFAI electronic version?

Got them in addition to the printed materials for L1 June 2011, since I can carry my laptop around and read them. Is anyone using these?

I’m using the books and the online but the online isn’t as useful as I thought since you have to be online on their site or download their software to read offline… but their software doesn’t work on Kindle or android. A 7" table (android) or a kindle would be a lot easier to read on the subway than the text books.
