firewire is gone becuase
a) it is useless, just a marketing gimick that never got off the ground.
b) they are now using intel chipsets, so they can no longer decide what they want to put in them. this is basically just another pc with a webcam.
pcmcia was replaced with pcie like ^ said.
macbook sounds almost as stupid as might mouse.
anyway, were just a few weeks away from seeing a similairly speced "I7000" from dell for about $800. I know you guys hate to admit this, but you know its true.
Either way, good to finally see them start using a decent video card.
As for windows, as mentioned before, there is no BIOS, and they have blocked windows install cds from the bootup selector thingy. Im sure there is a way to get around that, but realistically, windows on a mac is just going to be a geeky thing that wont take off.
To anyone that likes OSX though, this is good news. Within a few months(possibly weeks, or even days) you will be able to buy a pc and run osx on it natively. If you want to triple boot osx/linux/vista, i think getting a pc will be the better option.
And to all you amd lovers, i think the sight of Otellini on the stage with jobs today pissed some dell people off, cause they are threatening to move to amd again.
