I was thinking about this, and after my initial "WTF" I can actually get on board with this under some circumstances, particularly when the item is very new. For instance I had a friend who purchased a new SD card, went on honeymoon, took lots of snaps, and it failed a few days after he got home before he'd had time to download anything off it, and he lost all the photos from his honeymoon.
Can't you buy HD devices that will download a card contents without a laptop. Also many will take a laptop too on holiday, or an ipad with a camera card import thing. It is very risky not backing it up! Also the camera can cause corruption of the card, so it may not be anything to do with the storage medium at all. Likewaise a harddrive could fail if there was a power spike or power supply problem, or just a problem with the computer etc.
The problem is that people need to take responsibility for their own data and making backups. Maybe they should sell harddrives and card with a special data protection warranty, to protect against this.
