Microsoft offers 'Switch to Windows Phone' app to Android users switching platforms
Just in case you're not sure what this app does, it takes the current list of apps on your Android phone and matches them up with their Windows Phone versions. If the exact title of an app is not available for Windows Phone, it will include a similar app. The list is then sent to the cloud where it awaits the purchase of your new Windows Phone. Once you have your new device in hand, you can retrieve the apps from the cloud.
Microsoft is really pushing the whole switching to Windows Phone campaign hard. A heavily edited 30 second version of the hilarious wedding day ad received air play Tuesday evening on Fox's highly rated Hell's Kitchen.
