MCE sells iBooks with DVD burners

MCE just announced they'd sell iBooks 900 12 and 14" where the original Combo is replaced with a 1x Superdrive.
They even accomplish the prowess to sell their DVD-R machines without increasing the price !
The 12" 900/DVD-R version cost $1299, the 14" 900/DVD-R $1499.
We don't know how they manage to get this miraculous result.
A very important last word about it: iDVD doesn't work with G3s !
