Why is there a significant difference in battery life on the Uno vs. the Duo?
On the Duo unit, the batteries last only 50 hours because the screen is a large graphic screen that draws more power. On the less expensive Uno, the battery life is about 300 hrs. The graphic screen zooms to a large font and allows you to see the marked (selected) text before it is copied or cut. On the Uno, the marked block has only block-markers.
