 It's Wednesday, September 26, 2012. I'm Addy Robertson. Dial STAR 83743 for 90 seconds on the Verge. Amazon and Barnes & Noble's endless game of one-upmanship continues today with a new pair of Nook tablets to compete against the Kindle Fire HD. The 7-inch Nook HD and 9-inch Nook HD Plus feature a redesigned interface based on Android 4.0. Barnes & Noble is emphasizing a much improved screen on both models, and the HD Plus actually has a 1080p full HD resolution. The bookseller also revealed the Nook Video Store with content deals from HBO, Viacom, Sony Pictures, and more. That's due out this fall. Both tablets will be available at the end of October, with the Nook HD starting at $199 and the HD Plus starting at $269. Pre-orders start now. Google Play has crossed the 25 billion download mark. The digital storefront, formerly known as the Android market, entered 2012 at just over 10 billion downloads. Needless to say, it's had the best year ever. For the next five days, Google will celebrate by offering top-tier apps for 25 cents each. Check out the Google Play Store for more details, naturally. Finally, starting tomorrow, Angry Birds fans will get to experience the other side of the pig war. In Bad Piggies, gamers must construct and pilot elaborate vehicles made up of objects like boxes, wheels, and fizzy soda bottles. It's a much slower and more methodical game than Angry Birds. Is it just as addictive, though? You'll have to find out tomorrow on iOS, Android, and Mac. And that's it for today's top stories. Coming up tomorrow, clamshell phones are making a comeback. Dear God, why?
