Price, weight and size preclude an optical drive. Netbooks are just a connection to the Internet and intended for convenience and travel, not to replace real notebook computers.
I've noticed a lot of hype about Netbooks and how popular they are becoming. I've also noticed that none of the netbooks I've seen advertised has a cd/dvd player. I can't understand why this portable device can't also be used for viewing a movie or pictures, or listening to music. It seems like a natural. I've got to be missing something. Is the objective of having a small computer only to view email and simple documents? Please set me straight.
