Once again you mac zealots are blinded by your silly faith to Apple and have to poo-poo nightdweller's point without stopping to think. It's sad to see how people rationalize a missing feature in a supposedly top-of-the-line notebook. Go look at other notebook manufacturers and you'll find many supporting dual-layer dvd drives along with other superior hardware specs. Sony, HP, Compaq, and Actius just to name a few.
Funny how Steve Jobs proclaimed 2003 the year of the notebook as notebook computers were becoming more powerful, widescreens were being adopted, and upper level hardware was being implemented. The rest of the industry gets it and has being moving along swiftly, while Apple is still dragging the lackluster G4 to death in their PB line, let alone using the sub-par specs in their current notebook line.
So yeah, you have your portability. Good for you. But don't make it seem like a tradeoff because there is none. Don't even get me started on prices because that's another losing battle for Apple.
