    Hi everyone, from reading all the announcements, I am assuming that thunderbolt is exclusive to the new MBPs, but can someone (ideally with a link to show) confirm that there is no backwards compatibility on older Mini DisplayPort Macs? I wouldn't put it past Apple to extend compatibility but keep quiet about it so more people upgrade!

    Sorry if this has already been covered but I mroogled and couldn't find an answer.

    What? Thunderbolt is an entirely different interface that has the same form factor as the MiniDisplay Port in Apple's implementation of Light Peak. It will work fine as a standard MiniDisplay Port.

    That's great - thanks. That was what I assumed all along but I wasn't going to take it as writ until I read it somewhere.

    I'm increasingly tempted by the i7 13" but I think I'll stick with my 2008 unibody until the next revision. By the time they update the design there might just be some thunderbolt peripherals worth having.

    Sorry if I wasn't clear Miles; I was asking if pre-2011 Macs were compatible with thunderbolt, not whether thunderbolt works with displays.
