Nokia, AT&T, Best Buy and Microsoft are all holding hands and singing the same song about Nokia's Booklet 3G today. The good news is that the device will be subsidized by AT&T, at $299 with a 2-year contract at a $60 a month data plan -- with other rate plans and prices to be announced -- and a $599 non-subsidized price. It'll be out with the launch of Windows 7 on October 22nd and available through exclusively through Best Buy through the holidays. Nokia's also pretty strong about stating that 12 hour battery life isn't a "brochure number" but a real number -- though we doubt that since Nokia is using Mobile Mark '07 which doesn't include wireless in its base tests.Filed under: Laptops
