I was in the apple store tonight, playing with the powerbooks. There were about 5 employees standing around, doing nothing. This lady walks up to me and asks what the differences are between ibooks and powerbooks. All I could think of for the 12"s was that you could run dual displays, and the powerbook is slightly faster. I couldnt think of anything else. A little later this guy was asking about a 12" PB to an employee. He asks how much memory is on stuck on board, the guy says 512. I knew that the guy was asking how much memory could be upgraded, but I didnt want to correct the employee. Now I kinda understand how the employees may seem like they dont know, but really they are just tryign to simplify stuff for non-geeks.
