You need a week? It takes me just a few minutes to an hour to realize that the environment on any of the Android based devices is not for me...the short period of time doesn't make my opinion in more or less legitimate than your own (or any person's who has used an android based device for an extended period of time), it just means that i know what i like, and that isn't it. I had my brother's Galaxy S4 for about 10min., checking out the "new" features and gizmos, and even tried to allow myself to find some kind of comfort within that system...it just didn't happen...it wouldn't matter if i had it for an hour, a day, a week or a month...the system would be the same, and my opinion wouldn't change.
The Galaxy line is a great set of devices (as is the note), the OS is garbage to me.
