Thanks for the information. Just what I wanted to know.

I am not very computer tech savvy so, please allow me a 2 basic question.

I am thinking of getting a Nexus7 mainly  for 2 purposes:  To replace my NookColor which I used as an e-reader  and to have for wifi when I travel.     No games, possibly for watching Netflix and listening to music via Pandora or Spotify.

Question 1:   Looking at the  books available (or in this case, not available) on Google, I will be purchasing most books from Amazon     How easy it is to obtain the books through Amazon?

Question 2: I would also like to use my Kingston USB thumb drives occasionally to view some documents I store on these USB drives.
I've am confused reading the various postings and  specs on Google regarding USB.  Is it possible to use a thumb drive and simple put it into the Nexus 7?     And, if the answer is yes, will I be able to view these (microsoft excel and word documents) since Windows won't be installed in the Nexus7?
If this is not possible, I assume I could get them off my Google Drive cloud storage account.  Would they be available for viewing from the cloud account without again, since Windows won't be installed?

Thanks
