I may give them a try. On this subject, does anyone know what's up with Juice Defender? I read somewhere that the premium version did not work with the Thunderbolt, but I don't think the free version does either. I enable it and it seems to start. When I go back to check it it has been disabled. Am I missing a step or something? It looks good and as though the developer spent a lot of time on it. I uninstalled it, but wanted to give it a try too.
Startup Cleaner, is that an app killer? I've heard those are pretty useless. Have you tried Powermax by itself? I'm going to go with Powermax alone at first.
