At $79 Apple offers a very limited external optical unit. It's USB 2.0 only and can only read/burn CD's and DVD's. More importantly, it doesn't work on older Macs!
For the same price you can have a USB 2.0 external CD/DVD and Blu-ray unit. It's the same size, can do everything a SuperDrive can and supports Blu-ray as well, reading and burning. This doesn't only give you the option to watch Blu-ray movies on your Mac but you can store data on Blu-ray discs of up to 100GB on a single disc! Spend s few more bucks and you can have an external Blu-ray unit with USB 2.0, 3.0, Firewire and eSATA so it can be used with a wide variety of Macs. You can also replace your internal optical drive with a blu-ray unit.
It's a much better deal than Apple's outdated SuperDrive.
