Do apps which I have purchased on either the Android or the Amazon App Store for my Motorola Droid have to be repurchased on my tablet? Or, if I sign in with the same account can I download those apps to both devices? I ordered a tablet yesterday and it will be a week or so before I get it. I am asking primarily because I would like to have access to the games Amazon is giving away daily on my new tablet. So I would like to know if I need to sign up for a second Amazon App Store account now.
