With the last several updates, my edge has really improved. The battery typically lasts me a whole day of use, with me plugging it in to charge in the evenings. My typical edge use consists of the browser, Readerscope ap (great rss app), and the ereader. Perhaps more active android use might wear it out faster.

The keyboard is a big improvement too, I'm really enjoying tthe bigger keys and better response.

Keep up the improvements!
