Portable New Yorker

Emdashes reports that the New Yorker will soon sell the Complete New Yorker on portable hard drive in addition to the DVD set already on sale. For $299 you get an installation CD and a portable 3″x5″ drive. Since $59.99 gets you the same coverage on DVD, I’m curious about their target audience with this venture. My other question’s been answered though; the description includes this: “Plus, there is plenty of extra room on the drive for future updates.”
