So half the screen is wasted with weather?
What that SS does not show is how laggy Android is. How inconsistent the interface is and how bad it becomes after a few weeks/months of use. The integration between hardware/software is not nearly as refined as it is on the iPhone. The experience will never be the same.
That's not to say that they can't co-exist. You like Android, I like iOS. Unless Apple does something stupid, I would never switch. Google is just all over and they don't ever really "FINISH" anything. It's annoying.
Weather takes up a portion of the home screen only if you want it too. You don't need that there if you don't want it. You can download an iOS theme and make it look like iOS if you want. Not many people do though.
Lag is all but gone IMO. Plus Android operates a bit differently. This used to be one of my major gripes but I haven't found that to be an issue since ICS. JB supposedly got even better but I didn't notice much/any difference.
What do you mean by not finishing anything though?
