I'm an App launching fan. Widgets are distracting on the home screen. The SIII only has four lines of apps (not including dock, and there's room for more), and the default weather widget fills half the screen. The screen looks so awkward with these three row widgets with an awkward gap in the screen.
If done well, the widgets are fine, especially with a vanilla android application, but I neither miss them nor would I use them in an iOS setting, unless something reall drastic is done.
