When the news broke that Nokia had entered an alliance with Microsoft to make Windows Phone 7 handsets exclusively, everyone thought it was a headslap moment. Now the word is out as to what Microsoft had to do to sweeten the deal. Microsoft will pay Nokia more than $1 Billion to promote and develop Windows Phone 7 handsets. In return, Nokia will rebate back a fee to Redmond for every copy of Windows used on it's phones. The $1 Billion dollar payment was designed to not only keep Nokia from jumping on the Android bandwagon, but will also help to offset the amount lost by Nokia to focus exclusively on the Windows Phone 7 platform.
