Have you used the new TouchWiz 3.0? If not, then that point of yours is invalid. So many people are dissing this phone because of the TouchWiz interface, when they haven't even used the newest version which seems to be optimized.
Also, do any of you think of regular consumers? The non-power android users would probably like TouchWiz. It's interface is similar to the iPhone's which is a plus because the iPhone's UI is great. But hey, maybe I'm just the only one that thinks that way.
