Top: New MacBook, Middle: MacBook Pro, Bottom: Old MacBook

FireWire is gone! If you need FireWire, now only a MacBook Pro will do.

Also gone is an IR port for a remote. As far as we know, that makes the MacBook the only currently shipping Apple laptop that doesn't support a remote.

There's also no external battery indicator, a feature borrowed from the MacBook Air.

Apple has also replaced Mini-DVI with Mini DisplayPort, and replaced the two audio jacks with a single audio in/out port.
