DVDs… how should I put this… are “Good enough.” Which usually trumps Better.
As my job has me working with decently tech aware elementary school teachers… no, no the optical drive is not going away. Just as the DVD has not keeled over and meekly slunk into the shadow of BlueRay. “Burning” has been with us over a decade in a very reliable and user friendly way… at least with Apple.
I believe XKCD had a comic to something like this effect.

While that’s flash drive a DVD or CD works just the same and can, believe it or not, be mailed to luddite family members for playback in whatever setup they have. The death of iDVD is one I consider a serious loss to the iLife Suit. Every year like clockwork I assist teachers in the lower grades prep-and-burn copies of the Kindergarten and 1st grade “promotion” events for the proud parents. Many of whom do not have home computers nor any way to use a USB flash drive. DVDs still make more sense in a wider world outside the tech-centric on this site (and others like) belong to.
Could I setup a service where some of these parents could download the video to their “smart” phone. Possibly, but that assumes both the Parents and the School IT are up to finagling that as opposed to just following current practice of hard media. Very few schools and districts are up to this task, let alone dealing with Parents who couldn’t find their way out of a wet paper bag if the instructions were being yelled at them over a megaphone. Handing them a cheap DVD is by far the easiest “it just works” solution for them. And as long as I (as the guy helping prep the DVDs) put the same attention to detail (making sure there are chapter breaks at good spots) that Apple general shows, then we have a Win that the parents will remember for years and hopefully be more engaged with us as a school.
