Writing for InfoWorld, Tom Yager reports that he shelved his IBM ThinkPad for a PowerBook G4. Yager said that a long business trip gave him plenty of time to immerse himself in Mac OS X. “I started exploring the PowerBook and Mac OS X on the plane. Four hours later, I was still exploring and the battery meter said I had 30 minutes left. I was using Microsoft Office X and knocking around in Apple’s development tools… Since I got back from my trip, I have continued to use the PowerBook G4 by choice. I hadn’t reached for my ThinkPad again until I wrote a feature on notebooks, when I opened the ThinkPad, checked the model number, and closed it again. Without realizing it, I had switched.”
