I've gone and lost my laptop. Against my usual practise, I put it in the overhead container on the train home this evening...and only noticed I hadn't taken it down again and with me when I arrived home. I called Left Luggage immediately, but unfortunately, no one had handed it in (yet). I'll have to try them again first thing tomorrow, because really, I need it. All the work I've done in the last 6 months, it's all saved to 'On My Mac', which means that without it, I won't be able to proceed with any of it.
