you could have 2 usb ports and an ethernet port built in, and I'm *fairly* certain it won't add real estate. Taking out the cd-rom, vga port, enclosing the HD...all moves I understand to make it 1/8 of a mm...or whatever. But with the USB/ethernet, I don't get it. I suppose I'd have to crack one open and look at the MB to figure it out. My $0.02. Like others, I like mac...but I don't understand this product (minus the coolness factor).
