On a related note, Dell have a wonderful adapter in the US: http://accessories.us.dell.com/sna/p...&mfgpid=192401
It can run off mains or battery, so I can use it on the plane as well as the office. BUT I'm in the UK and they don't list it on the Dell UK site. And I can't tell what similar item might exist I can use, because nothing lists Vostro as a compatibility... probably because it is a new range.

Any help? I don't want to have to order one from the US...
