This happened about a month ago:
I managed to srew up and totally miss my, train, which was apparently the last one today, balls. It wasn't entirely my fault, I was on a Boris bike and there were no free slots at the first station, that cost me 10 minutes; and then I couldn't find the platform.
Anyway, I was feeling totally like Lisbeth Salander, sitting on a train platform late at night with a stupidly high-value amount of gadgets. (£500 iphone, £500 camera, £200 netbook, £80 wi-fi dongle) Now, put yourself in my shoes.
You needed to check the subsequent trains so pulled out your phone.
Bad luck, your battery is about to die. Shit, pull out laptop to charge it or make a note of the numbers to call to say you'll be home late.
Your laptop take 20 MINUTES to boot cos it's windows and it's gotta install some shit. Lukily your phone doesn't die and you got time to spare. Grab usb cable and plug phone in.
You forgot, your usb cable is trashed and doesn't conect to your computer, it won't even charge it, and the replacement you ordered a week ago hasn't arrived yet. So no charging, or tethering, for you. Not to worry, make a note of the numbers, then use your wi-fi dongle and use skype.
Bad luck, dongle's got no credit. No problem! You've got a credit card.
Bad luck, 3's top-up page needs to connect to an external security site to authenticate you, and you've got no data remember. Ok ok, there's a payphone over there, you've got the necessary 60p change.
Unfortunately they only take four coins, and you have four 5ps and two twentys. GOOD NEWS you find a 20p in your pocket.
However when you get through it's a shit line and you're calling a mobile, so you get about 30 seconds and don't manage to communicate the problem. Shit cakes. No problem! You're on a train station, there's pigeons everywhere, catch one and send a message! Bad luck..... etc ad infinitum
Now, obviously I didn't plan my equipment with several layers of redundancy, and normally my phone is my only communication method, but I was amused that everything I thought would allow me to contact the necessary persons managed to fail all at the same time.
