Hardware development companies can boost the trade of their products, a vivid example is the Dell company that will launch the Windows 7 with its touch screen as there will be an operating system that supports it.
It will not bring support or compatibility with obsolete technology drivers and devices
It would not be a total innovation, due to having features of other operating systems, such as the micro-kernel that is already part of the Mac OS Tiger and also took part of the graphic interface of it.
