Today's announcement basically describes an alliance of sorts between one of China's most mature x86 tablet manufacturers and the world's leading x86 software developer. Zhang Xuejun, president of Hanvon, has indicated that for them, the tablet is very much a business tool as opposed to an entertainment or content consumption device. He goes on to mention how business users will demand a Windows OS on their tablets and hopes that this alliance will bring plentiful dividends in the future.
Hanvon have already released their first tablet. The Hanvon Touchpad is a 10" Win7 tablet running on a 1.3GHz CPU. If you look at the specs you'll see that this is a not a light machine. Obviously it's intended for the mobile user who needs a lot of ability and is willing to sacrifice weight and battery life to get it.
