One thing to point out is that the number of Windows 7 PC is not 100% related to the Windows RT app user base.
- A significant amount of those PCs are in work environment, that users do not want to install apps like Mad Faultry.
- Majority of the PC's do not have touch screens or even a touch pad. The whole touch-based RT app becomes akward to use.
- Most of the mobile PC's are thick, heavy, short battery life, and people have iPads, Android tabets that they do not see their mobile PC's as tablets.
