I've never needed power widgets. In fact just about everything I need is already on the Lith Mod. If they would update the News/Weather widgets and a few other things google has enhanced it would be nice. Otherwise I'm very happy with it.
It's fast and smooth and LauncherPro just added some wonderful paging effects.
My only problem is my available internal memory is too low. But there are lots of things I can't move to the SD because they run all the time or because they are widgets.
