For that small minority of sensible people who own a Mac you can pop over to the Apple site and download FaceTime so you can talk online to your similarly sensible friends and family. Less sensible people can use Skype of course, but it's not quite the same.
So here are me and Tish having our first FaceTime chat this afternoon; that's little me in the corner looking askance at Dunk who is messing with the keyboard to take this screenshot of the momentous occasion. It was fun, kind of like a cross between a real face-to-face conversation and a phone call.
Now back to the packing.
