Microsoft + Apple .... what if?

So Microsoft is once again copying one of the the greatest ideas in history from their one and only rival Apple. They're copying the IPOD and calling it the Zune. They've modeled their Windows OS from Apple for those who didn't know. I'm thinking why don't they just merge. I bet no ones thought about it. It's a billion dollar idea!!!!! Microsoft has the mass market while Apple has a dependable and more reliable platform. I'm a genius!
