Getgo,
I have one of the previous models of the Fujitsu (the 2120P). It was my "go-everywhere" laptop. It was much slower than the one you are looking at, but it served me well for 2 years.
However, I'm replying to you on my new "go everywhere" laptop .... an Apple PB G4 12" . Yup, replaced the Fujitsu with a PB (my very first Mac, no less).
Why did I switch? Lots of reasons, but the main ones were the display size on the Fujitsu started to get to me and the PB keyboard is much better. And this was a BIG switch .... I've used PCs for > 15 years and self-built over 30 of them.
The PB size, form and function is outstanding .... and OS X is, well, *fun* to use. I smile every time I take this machine out. I figure that if you have to work on the road you might as well enjoy it ! I may have bought my last PC ....next year maybe a dual G5, who knows?
Oh, and if you want to save some bucks, we have a G4 iBook at work .... it's an impressive machine as well. Built like a tank.
Good luck with your decision, it's a great time to switch and an iBook or PB is a great way to test the Macintosh "waters".
