Firewire is practically dead with the introduction of usb 2.0...usb 2.0 is 80mbps faster than firewire 400 in the first place...I personally just bought the macbook and am very impressed with it. I previously owned the Air...which by the way works very well with the disc share utility, I never had any problems with burning music onto it using my 24" imac.

In my opinion, you cannot compare a mac to a pc on hardware alone...The main reason I switched all of the computers I own over to mac is Leopard...I would never even consider buying a Vista machine again no matter how cheap it was...The operating system alone is worth the more expensive price tag.
