Better battery power indicator and task manager than the built in utilities on the BJ2. Of course I found out much later that just holding the "Home" button down for a few seconds will launch the internal task manager anyway to kill off tasks.

31-day free trial, which I'll let expire, since these features already duplicate other tools which do just as good a job.

It's only $4.95 to buy a copy though, but it's not worth paying $4.95 for a different interface for tools I already have access to.
