Dell executive Jeffrey Clarke supposedly told Microsoft CEO Steve Ballmer that the ARM-based operating system of Windows should not be called Windows RT. However Ballmer said that the Windows brand is too important not to used in new devices.
Clarke claimed that he explained to Ballmer that the term Windows should be used when it is compatible with normal Windows applications. Windows RT does not support normal Windows applications. Both versions of Windows can run “Metro” apps, but Windows RT cannot run normal Windows applications.
Dell vice president Neil Hand said that it would not have mattered if Microsoft called the tablet version of the operating system by another name, PCs and tablet manufacturers would still need to explain the differences between the two operating systems.
