I paid for a IM+ myself, and then switched to JiveTalk. I agree on all points. JiveTalk has a simplicity going for it, and battery life is something I watch. Some applications can destroy it. Some applications have memory leaks. Some applications are just harder than they need to be. JiveTalk is one of those apps where using it for week will make anyone love it. Great app. The only IM client I use.
