Dude, you can't even RUN modern apps on Windows 7. You have LESS options in Windoes 7. At least in Windows 8, you can run Windows 7 apps and if you ever need to you have the OPTION of running Windows 8 apps. Windows 7 has no OPTIONS. Windows 7 gives you NO CHOICE.
So you are saying, because Windows 8 is restricting, you will go back to Windows 7 which is even MORE limited? That doesn't make much sense.
Actually, it's MS restricting the store to W8. Then again, what kind of enthusiast would run "modern apps" when you can use full-fledged programs on anything that doesn't use touch-input.
