Surely, this must be a joke. Backing up hundreds of gigs to optical in 4GB chunks would be an incredible waste of time. Don't even want to think about the organizational effort involved to be able to find anything in that monstrous pile of incremental backups.
No freakin' thank you.
And who the hell bothers ripping DVDs in the HD era? Complete waste of time.
no, I wasn't joking. Backing up family photos and videos taken on my DSLR is easy with DVDs. Especially for off site storage of them. I can simply burn a new disc at any time and drop it off at my parent's house at any time. Seems easier than making a trip over to pick up an external HDD, taking it home to do a backup, then returning it off site. I have a copy on an external drive here at home that I only pull out of the fire-safe when I need to do a backup.
As for DVDs in an HD era, it is a hell of a lot cheaper ripping DVDs that we already own than paying for them again from iTunes. The DVD is more flexible anyway. Portable DVD player in the car, taking it to Grandma's house. Not everyone has an AppleTV or similar for streaming HD rentals to the TV. Besides, I jumped into HD early, so my TV is a 720p/1080i 42in plasma. DVDs still look fine on them, even if I rip them and play them on the xbox.
Apple needs to cover the vast majority in order to move the most product. Don't make the assumption that your life, values and needs are the same as everyone else. You just make an Ass out of U.
