Slasher, you mentioned the various power adapters, but you forgot about the telephone sockets!
I recently "invested" in a "road warrior's travel adapter kit" from CompUSA (while travelling with my laptop!) All in a nice case, marginally smaller than the one for my laptop (plus modem cable, mouse - I HATE "scratchpads" - charger, cellphone, charger for same, cellphone modem adapter - won't work in USA of course, different cellphone frequency)
There's power adapters to cover MOST countries - not Dununda as they have a plug that NOBODY else uses! - but a really impressive selection of TEN different phone jack adapters - many of which I have NEVER seen before! There's also a nice little card to tell me what countries I have to visit to try out the phone adapters that I have never seen before!!
CompUSA - How about sending me a $50 voucher for the advertising? (advertizing?) Please mail it via my postbox in PPRuNe Towers!
