Macbooks no longer have the Firewire ports - you have to go up to the Pro for that.What makes you say that?
The point of the macbook air is to keep it light by leaving things out - like a drive and multiple ports.
Every production mac - laptop and desktop - has firewire.
If anything, it appears that mac is going for faster firewire - the old macbook used FW400 and ALL the new ones use FW800...
Apple does have a habit of being a leader when it comes to moving into and out of technologies.Do you think that this indicates a move away from firewire or the macbook?
I have read there will be a retro fit PCI USB 3 card for mac pro's.I've read that Apple may (or may not) be interested in eventually migrating to Light Peak connections.
