I was traveling quite a bit last year for work. Left a client in Tuscon and discovered that I had forgotten my charger!! Yikes.
Well, I barely survived the next two days on minimal charge. Then flew to LA to visit family and bought one at the MacMall in Santa Monica.
Two weeks later, I left the charger at home. Since it was on a Monday, there was no way I would last the week...so a long drive (60 miles one way) to the nearest place that I could get another one.
Yikes. Wish there was another way to charge an iBook.
