And it's a shame because the cost of including FW in a $1299 laptop is negligible. I'm not an expert in technology, but I'm guessing the controller chips(re: southbridge, northbridge ?) already are capable of handling FW so it is a matter of adding traces on the motherboard, adding a FW chip and a port.
Again, I'm guessing, but I doubt it would cost $20.
$20 wasn't the issue, 0.13in was. This isn't any kind of technically issue, it's a design issue. Ive wanted a certain design and Apple cut out a feature to meet the space allowed by that design.
