What's with you people and the need for an optical drive???? Obviously such laptop would not be your only machine, you are looking at a market where someone has the power they want at home or at work (be it a iMac or a MacPro) and they want the portability outside. Personnally, I would be willing to even ditch the Ethernet card in such laptop if that can save some space and allow it to run cooler (my main issue with my PB).
