"Horribly inefficient operating system."0.5 starson by bjs1701d
Pros: None. Unless you want to run tablet apps on a desktop computer.
Cons: No visual pizzaz. Removes aero glass. Takes desktop computing back to 1991. Where everything was two dimensional and people didn't know how to make attractive user interfaces.
Summary: This product is just a ploy by MS to leverage Windows popularity vis-a-vis persuading developers to write apps for Windows phones and tablets. Consumers are made to suffer in the short term as a result, via being forced to use an OS that was designed for tablets on a desktop computer.
