This clip was shot on a Blackberry Playbook tablet. Both audio and video quality are exceptional given the hardware involved. And the small form factor makes it far more likely that you'll have it with you when you need it than with prosumer camcorder equipment. It certainly can't replace higher end gear for much of the work videographers do but it has opened up a place for itself in the YouTube universe. For the record I host client video on the Viddler platform because I can control the environment around it.
