Intel and Microsoft are counting a lot on the popular acceptance of the Windows 8 Ultrabook, which will be small, fast, relatively affordable, and do everything most people expect out of a portable computing device at least as well as the competition.
By combining the tablet favoring aspects of the Metro UI with the convenience of a keyboard and the additional power that the Ultrabook design brings along, Intel feels that the best of all worlds can be put together in one lightweight package.
The Ultrabook is still an interesting idea that may catch on big once there are more models available and exposure increases. The idea of a touch screen Ultrabook faces such an uphill battle that it may be hard to imagine it succeeding no matter what advantages Windows 8 offers by way of improvement.
Much of the potential success for this idea may rely on the ability of Windows 8 to take advantage of ARM device compatibility. Microsoft is already walking a fairly troublesome line by unifying the experience of the OS without finding a way to design for both ARM and Intel devices at once.
