If you get the nook...you can have up to 5 people under one acct..and everyone shares the books and apps.. so any apps I download on mine for my grandson..downloads on his also. Plus we can archive them to give us more storage space and take off items we don't want on ours. So our acct is shared with my mother, my hubby's mom, plus my daughter-in-law. Works out great... we can read the same book at the same time...or not. BUT we only pay one time, plus we can share for a few weeks with someone not on our acct. We have no issues reading outside with our nook either.
