Xbox 360 is currently the only own-brand product line that Microsoft has achieved success [with], while Zune media player, Kin smartphone and own-brand TVs all had unsatisfactory performance. However, Microsoft is still considering to launch an own-brand tablet PC and is proceeding on a low profile.
Microsoft began selling branded Tablet PCs 12 years ago, but the market was not ready and sales were light.
With the creation of Windows 8 however, Microsoft is building an operating system that works for desktops, but has many features optimized for tablets, which have exploded in popularity since the launch of the Apple iPad.
