Disposable Digital storage ?

Sandisk is now coming out with disposable write once storage, is this changing anything, I dont think so. there are really only two reasons I can see how this will work. For one if your going on vacation and want a back up just in case, and two if you put some music on it and place it in your PDA which no one ever seams to have any more (except on ebey) ... I got this story from Endgaget written by Thomas Ricker
