I see what you're saying.
The idea behind my concept was, it could maybe work for both touch and non-touch screens. I thought maybe having a start menu that gave you customizable tiles would be nice, because right from the Start menu, the live tiles could give you the weather forecast, see friend updates on Facebook, control your music, or get a glimpse of your email/calendar events. Think of it as like having Android widgets in your Start Menu. Plus, you would be able to resize them to be as big or as small as you prefer. I like the idea of integrating a variety of different internet services that the user wants into their desktop environment, so they don't even need to open a web browser to access them.
There's also an "All Apps" button next to the search bar, which would change the entire menu to show a list of your installed programs, just like in Windows 7.
