Google overhauling the Android Market UI again

The Market UI overhaul will bring a new homescreen with easy access to apps, games, movies, and books. When you begin to drill down, you'll find the usual Categories, Top Paid, Top Free, Top Grossing, and Just In lists that we've come to expect, but you'll also find easy access to an Editor's Choice list and Staff Picks.
An interesting note that Google casually tossed into the preview video for the new Market is that Google is claiming their bookstore has the "largest collection of digital books" on your phone. Google is still claiming over 3 million books in their store, compared to just under 1 million in the Kindle store.
