I have used this non stop practically, since it arrived.  I don't miss the CD/DVD tray because I really don't have a lot of cause for it.  I have streamed video's from Prime and the quality is wonderful.  It's so lightweight you can take it anywhere.  It loads up quickly and is great fun to use.There are numerous programs that you can download from the Google Play Store.  There isn't a pre-loaded writing program, or games, etc.  I downloaded a notebook program, calculator, Bible, etc.  The e-mail is obviously Gmail.  Basically you can add any program available, however, I'm not familiar with a ton of them.
