Let's be even more realistic. Sync'ing one's palm or Treo or what ever before hopping into the sedan and heading out to play road warrior against the competition is a far more impactful situation financially than being able to see one's OS X desktop behind a Windows application. Nobody has ever earned a dime or beat out the competition by having a healthy coherence enabled environment. What people need to pay bills is functionality - they need their calendars, their appointment books, their Tom Tom, chatty GPS, etc. Coherence is just damned cute and junk and lord don't you and I just love it, but it's not - hell it's not even close to being the killer app in the VM enabled world. Imagine this - PHB: "Schmedley, Schmedley! - where's your presentation on B2B secure communications? Schmedely: Well, sir, actually, I thought I'd discuss coherence on the Mac desktop today, sir."
