David du Chemin has a post up about the hyperdrive he bought. Sounds like something you add to your car to get you 400 miles in 4 minutes (I wish) but it is a on site backup device. I have wanted one of these, not that I would really use it that much, but they still come in handy. Would have been great on my summer vacation. Epson makes the P-5000 that will store 80 gigs for OVER $600. Yikes. I am buying a lens before that. Amazon lists the 40 gig model for $279 and the 100 gig for $319. Much more reasonable. Not as big a screen, but getting approachable in price.
