The same could be said of the Start Menu.
At the top is the shortcut for my car key. Next is the one for my house key. This is the one for my mistress's apartment key. They're arranged on my menu to my preference, just like you've arrange tiles on your Start screen. Like the W8 Start screen, the W7 Start Menu appear with the push of one button; indeed, it's the exact same 'Windows' button.
For some, the Start Menu has the comfort of familiarity (me included), but that doesn't make it better. But to my untrained eye, both appear to have the same feature set.
I keep all my keys on one key ring, by the way.
