That's a lovely looking piece of kit, have you had the opportunity to play with one?
The one problem I remember seeing was when somebody's laptop was running it and went to sleep and they weren't able to get it to resume the job when it woke up. Maybe there's a way to do it, but just making sure your computer is set to stay awake avoids the issue entirely.
At least that's my understanding of it. I've never used it myself, only watched it run for other people.
