I would give it a try,
From what I've read ( I haven't tried it yet but I'm looking to now that you've brought it to my attention) it will run a virtual environment that captures the disk writes without altering your system unless you say it's okay.
It looks like it could be a great line of defense against malicious software and whatnot and provides a nice looking testing environment for programs you are unsure of running on your machine or for browsing suspicious sites (which you probably shouldn't be doing anyway

)
