Launchers have been a rather hot topic for Android users lately. There has been two recent arrivals, though, they are both still in private beta at the moment. The launchers are Themer and Aviate. We took a took at Themer last week and more recently, an invite to Aviate has arrived. We have only spent about a day with Aviate so far, and while we have some issues, there does appear to be some potential.
