Yep, use the pay version all the time with our RMM tool to script automatic install & updates of applications. Great being able to click a button which sends an install job to the computer; then tell client it will be available for you in about five minutes whilst getting on with some actual work. Even better when setting up a new computer, script to install all the standard applications automatically.
I think pro version costs about $50 per month, peanuts when I know how much time it saves me.
