Launcher 7 is an attempt to replicate the simplicity of Windows Phone 7’s launcher on an Android device, and it does a great job. There are others out there (like Windows Phone Android), but Timo Kujala’s Launcher 7 easily takes the cake. From live tiles to widgets to transition animations, Launcher 7 is the way to go for someone who wants a simple launcher or who loves the look and feel of Windows Phone 7, but doesn’t want to leave the Android fold.
