If you don't have either yet then I'd say go for the motion. It's a super cheap for what it is. If you already have the connect then keep it. The motion small screen and low ppi sucks if you like to wstch videos (like me). The gs3 is supposed to be here as early as this Friday and that's the only one worth leaving the connect for.
People who leave one star ratings in playstore because of something like not liking the icon should be beaten. And forever banned from using free apps.
