  (Asked by: username_0 on 2012-06-21)
  
  I'm interested in purchasing a camera setup for video where I just "tether" a camera with realtime HDMI or USB output to a PC (a netbook) with a huge hard drive and shoot everything directly to the netbook.
  
  Why? So that I can experiment with visual effects in realtime, and get excellent macro-command functionality and web uploading for "free".
  
  Do any of you have personal experience with this kind of setup and have anything to say to dissuade me from trying it?
