It's like a Flowbie for your face!
The Philips Norelco vacuum trimmers are the only ones of their kind that I know of, so if this sort of thing interests you, you're looking at just about your only option. They make lazy trimming far less annoying by vacuuming the majority of clippings into an easily-emptied chamber, and Philips Norelco appears to be making them more solid than previous incarnations.
