Since the iBook wasn't able to stay for the duration of my evaluation, I apologize that I couldn't get comparison photos with all four notebooks at once. Figure 1 shows how the iBook, Fujitsu P7010 and my current "reference" Dell Inspiron 4100 literally stack up while Figure 2 does the same for the P7010 and Dell with the Fujitsu S2020.

The P7010 is definitely the smallest and lightest of the bunch and, of course, the most expensive and really out of my desired price range. But I couldn't resist checking it out in hope that its size and weight advantages would win me over.

The iBook was a bit thicker than I'd like even though its ~5 pound weight was lighter than the Dell's. But I was surprised that the less than 1 pound difference between it and the S2020 really was noticeable.

Figure 2 shows that the S2020's footprint isn't really that much smaller than the Inspiron's. But Figure 3 shows that it's definitely thinner, and surprisingly, about as thin as the P7010!
