USB Charging

Now... I travel a lot and I have a standard Travel Pack of electronic gizmo's that I like to take with me, these are Mobile Phone, iPod and Nintendo DS.

Luckily all of these will charge through a USB port on my laptop, so in theory I would need to take one cable, but no how wrong can you be, each one of them has their own style of USB end that plugs into them, and none of them are in the format of a standard square USB or Mini USB connector, so there are at least 5 variants that I am aware of.

Come on manufactures sort yourselves out and settle on one format, today I need to carry 3 different cables.
