It's not just Apple who have already abandoned internal drives. There is an increasing number of PC companies who have noticed that optical drive is not essential as before. In this article, I will talk about the reasons why Apple sell MacBook without a CD/DVD driver.
Thin and Light
Apple is obsessed with making their computers (Actually all their products) thin and light with super long battery life. To reach their purpose, Apple decided to cancel some unnecessary functions, one of them is the optical drive. Because it makes computer heavy and bulky and it is left unused most of the time.
In order to make their computers more durable, Apple has slowly gotten rid of moving parts. The more moving parts a computer has, the more likely those parts are to fail. The current machines have one moving part: the fan. It makes for a very long-lasting machine.
The Pusher of Industry's Market
Apple is known for pushing the industry where they want it to go, with mixed results. You saw that with USB, the mouse, the CD drive, the floppy drive, etc. Some of these Apple both made mainstream and then ditched. They haven't been so successful with others, like Firewire and Thunderbolt.
CD Drive Unnecessary
In modern life, optical drives are no longer necessary for people. You may ask, what if I want to play my classic Mozart album on my computer but there is no optical drive for it. Then the apple salesman will ask you back, how often do you need to play a disc when almost all songs are on the streaming medias? At this time, you will get your epiphany on the question “Do I really need a laptop with an optical drive?” The answer is obviously, no.
Digital Downloads instead of a Disc
Many people (including the folks at Apple and Google) view CD's and DVD's as a nearly obsolete technology. Most businesses and companies do everything via the Internet or on thumb drives. Music, books, and videos can be legally downloaded or streamed through the Internet. With the rise of the Windows and Mac App stores, owning a CD drive is no longer the only way to get quality software.
The CD drive is very fragile, and it was so difficult carrying these things around that mine was broken by the time I traveled. That’s why you need a portable CD/DVD Player.
So it's worth the trade-off. In order to enhance the user experience for the product, seems like it’s not necessary to keep some features that just a few people need. If you're minority people who still need an optical drive, I recommend you buy a portable CD/DVD Player or home CD/DVD Player.
