It’s probably not a popular opinion on a forum dedicated to Apple products, but Microsoft’s “Live Tiles” interface was pretty dang awesome…especially on Windows Phone 7, which still featured hooks into Facebook and such that would allow you to easily see status updates from the people you cared most about without all the other noise.
Now, the App Store stunk and most of the social features got stripped out as the OS “matured” into Windows Phone 8 and then 10, but the interface was slick.
No one’s ever come close to matching what Palm achieved with WebOS, though. That was a mobile operating system way ahead of its time.
