Uh, the whole point of TB is more speed and more functions. There certainly isn't already a thunderbolt port on there. Its an mDP port, nothing more nothing less.
By your logic there are already USB 3.0 slots on there as well, they just need to make them faster and add a couple more pins for power
no, I just mean that there is already space for the thunderbolt port, there's no need to reduce the numbers of usb-ports as the text I was replying to implied...
you didn't get my point at all - I think if apple brings thunderbolt to the mba they will do it like they did on the mbp (by using the space the mDP already used). ok?
