PSI? Apparently it keeps up with all your software and let's you know when anything is out-of-date. Anyone ever use it.
I guess with things like this you gotta ask yourself do you really use THAT much software that needs to be updated THAT much that you can't just do it yourself? Or even better let the auto updaters that come with the vast majority of software these days do it. Which is my way of saying no, haven't used it, don't see the point.
