That the beauty of it (from a marketing point of view) - unlike the half-assed attempt by HP (here's a pdf reader that doesn't actually work, here a document editor that is useless), this has absolutely no emphasis on productivity.So, where's the productivity?
This is purely a consumption device. Yes you could load up quick office or similar but Amazon don't care if you do that and aren't marketing it for those purposes.
You want productivity? buy something else.
