RD, where do you get that upgraded iGo adapter? I was using a dell laptop with a power inverter before but I will switch to a thinkpad w/ docking station if I can get a dc adapter like you and Hark are mentioning.
I found a dc adapter claiming to fit thinkpads, on yahoo.

is it possible to get such an adapter directly w/ IBM brand on it?
