Could it be a cloning machine? That would be handy. I could send one of me out to work while the other gets on with the novel. Maybe a third me could do a spot of dusting. It's dog-hair hell over here.
Maybe it's a Star Trek/Dr Who style transporter? I could go back in time and tell my younger self to stop watching Dallas and start blithering well writing of an evening. At this rate, by the time I get published I'll be too decrepit to read what I've written.
Is it an Innovative laundry device? One that presses sheets, sorts socks into matching pairs and spits anything unfashionable into the bin. I hope not. We've no room for it.
An orthopaedic bed, with Futuristic side-table and, um, massaging device thingy?
Okay, I'm being silly. If you read the papers yesterday you'll know it's Blackwell's new Book Espresso, due to be launched this autumn. They'll be the first UK retailer to install the machine, which prints books on demand. It can access around one million titles, print, bind and trim paperback books with four-colour covers. In minutes.

Now I'm giving my age away.
