The 13-inch version of Apple's revamped MacBook Air doubles the USB ports (to two) and adds an SD card slot, but it still lacks an optical drive. And it's not alone--other recent DVD-free 13-inch systems include Toshiba Satellite T235D and the Asus U35JC.
In smaller 11- and 12-inch laptops, we're used to not having an optical drive, although they do occasionally turn up. But to some, the optical drive is becoming like the telephone modem jack that used to be standard on every laptop--a bit of legacy hardware that rarely gets used.
The main reasons we used to need an optical drive were for installing applications (including games), playing DVD movies, and burning backup discs. Thanks to painfully overenthusiastic DRM, games are much easier to download and install via an online service such as Steam; the same goes for many apps (including the ones we use frequently, including OpenOffice, Reason, and Pro Tools LE).
Even video content is much more convenient when downloaded from iTunes or streamed from Netflix. Backing up is now a task for a high-capacity USB key or networked hard drive.
But we also know there are many people out there who will never give up their laptop DVD drives, and they have sound reasons for feeling that way (we learned earlier this year that people have a similar attachment to their computer mice). Assuming optical drives are going to stick around for the time being in 15-inch and larger laptops, let's instead see how people feel about them in smaller systems.
