The desktop is 1 click or tap away. It takes maybe 1-2 seconds.
The Start screen is your Start menu.
it takes 3-5 minutes to find, download and install Classic Shell. It can do those things easily.
Windows 7 still works
As I've said before, when everything gets sorted out, they'll realize you have two separate interfaces, and never the twain shall meet. Simply pick the optimal one for the device you're using, and then you should never leave it. If using a desktop, Apps can launch from icons and when they do they'll be windowed. If using a tablet(especially one of the mini ones), perhaps the Mobile Interface is more your taste.
But they'll spin their wheels until they realize there isn't a unified interface that works for everyone. It simply doesn't work that way. Some people like channel surfing(Mobile Interface), others like control over what they watch on one screen. Its simply different tastes and tailored for different devices.
