Looks like a good start. Chris Day 19:42, 23 December 2008 (UTC)

Does anyone remember the right quote: real, virtual, etc.

Something like:

  • If it's there and you can touch it, it's real
  • If it's not there and you think you can touch it, it's virtual
  • If it's there but you don't notice it, it's transparent
  • If it's not there, you think you ought to be able to touch it, and you can't find it, sales has been at it again.
