No disk drive!!!!!

After reading the article Apple and the incredible vanishing CD drive ive learhened that Apples CD drive is vanishing each new MAC they create does not have a CD drive not but you can buy one for $79. ive also learned that the only computers in apples current line up is the MAC pro and the non retina display MAC book pro, but apple has stated that a new MAC pro will be released in 2013.KI have also learned that removing the optical drive saves the computer on space. One thing i liked about the article is  that it described the past and future of the MAC's. Another thing i like about the article were the pictures that were posted in the article. Why else would apple get rid of the disk drive?
