I think I'm going to have to buy one of the infernal devices known as Mobile Phones. I almost certainly won't use it much, making Pay As You Go cheaper- but does anyone have any advice as to who to buy a cheap but reliable one from? ("Features" other than SMS don't worry me that much).
Update: Apparently Asteroid 2004MN4 is going to miss the earth by a minimum of 64,000 km. It still rates a 1 on the Torino Scale, but I'm not too worried by a chance of hitting of 3.6*10-5 in 2053.
