I dont understand why people have rated this product badly. This macbook is revolutionary, its a subnotebook which offers much better performance than those it competes with. Its not meant to be a powerhouse, its designed to be a solution for people who need an ultra mobile laptop without giving up performance. I bought myself a superdrive for this and i havent used it once. Apple have also designed a piece of software that lets you use a dvd drive on any computer on the network, which just shows up in the finder (my computer, for windows users). As for the 80gb hard drive, if they were to put anything bigger in then it would mean using a 2.5" hard drive instead of a 1.8', which would compromise the design way too much.
The whole point in this laptop is to be ultra portable, which means taking stuff out to get the weight down. If your one of these people who criticize everything about this product then its obviously not for you, so dont buy it! This macbook is incredible, its an ideal solution for portability
