I suffer from that object fetish schizophrenia where I'm taken by very new things and very old things. Sketching on an iPad is awesome, and so is laying ink in a Moleskine. On my desk I've got a stack of rare internal documents from the Singer company circa 1920 or so, and it's being fed into a Canon scanner from 2010. I use a zig-zag sewing machine from 1953 and I use brand-new Schmetz needles that have the modern "scarf" cut into them.
Mac accessory-maker Twelve South's BookBook perfectly encapsulates the old/new thing. It's a laptop case taking the form of an ancient leatherbound book, offering both protection and scratching that vintage itch.
The company also touts it as making your MacBook less likely to be stolen, but that won't fly here in New York; I'll never forget my neighbor in Brooklyn being robbed so thoroughly they even took the sheets off of his bed. Still, I'm digging the BookBook, and now they've even got a little one that serves as a wallet and iPhone case.
