I decided to buy Beautiful widgets for the Plane Mode widget mainly but I was also curious what the difference was between "Weather Widget - Donate" and the "Beautiful Widget Home".
Both are flip clocks with weather and forecast. The Weather Widget - Donate with the free forecast add-on is much nicer in that it animates the picture of the sun or moon and clouds or weather when you tap it for the forecast just like on HTC Sense devices. Beautiful Widgets doesn't animate when you tap for the forecast. All of the other widgets that come with Beautiful Widgets still makes it a good purchase (a lot of quick settings toggles).
