OK, I confess - I like a gadget. I know this isn't going to be news to most of you, but there you go - I've finally "come out". Again.
The Guardian, bless it, does like lists of stuff, most of which I ignore. For reasons best know to the universe I looked at their gift guide for travellers, which is very strange given my opinions of that event. Much to my surprise this was in their (otherwise dull) list: The Scrubba. Looks most useful.
