Hi again, Bob. I'm looking forward to testing out Teleportation. I'd be interested to know if someone would put up a "howto" video. This seems like a real distinguishing feature from Parallels Desktop and VMware Fusion (or Workstation). I'm also glad to see the snapshot improvements. That's going to be huge for developer/QA types.
