I has two data cables in fact, since my first Ericsson copped it
and I replaced it with an identical one. Will keep one at work for charger emergencies.

The third one
Could be secreted in a handy bag, hat or pet for other non-work/non-home power-loss situations.

My bag is like the Tardis
so that could work very well since it contains everything in the known universe - notebook, phone, iPod, keys, tic-tacs, make-up, brush, ladies' things, spare belt, purse, camera, several pens, some missing their lids, and a few loose sherbet lemons.

My travel rucksack is the same
It currently contains, amongst other things:

Notepad and pen
Dictaphone
Business cards
Batteries
Copies of the latest magazine
Small Netbook
Unbreakable camera (currently on its second repair...)
First aid kit
A Guide to Russian Travel
Some bungees
A padlock
A sponge
A Warhammer book
A diary
An MP3 player
A European road map

It's got me through some interesting scenarios.

Bloody hell!
I did also use to carry a Swiss army knife but security at St Pancras don't tend to take kindly to having to confiscate such things so I had to take it out... usually there are one or two Lovefilm discs in there to be posted or something I need to take to work, too.

This is what I do
I have the charger at work and the data cable at home (since I'm more likely to transfer stuff to/from home pc than work pc.
