Although I'm not Razz I hope you don't mind me answering this question

.
The best example for a Factotum is probably Indiana Jones (which incidentally is also used as an example in the class description). He evades and disables traps, is a scholar using his knowledge to unearth secrets and find hidden treasures, wields a whip and his gun can be translated into casting very few spells.
The factotum is something I'd call a true adventurer. Someone who is able to adjust on the spot to the threats presented.
All in all I have to agree with Razz that the book is pretty neat. Somehow I expected Cityscape to be far better than Dungeonscape and it's quite faszinating that it turns out the other way. So far I only have read bits of the book (my friendly not so local games store shipped it two days ago) but what I've read is pretty good.
Particularly I liked the Alternative Monster Feats Section, which gives a examples for a few classic monsters how to improved them just by swapping out one or two feats. This will lead to some pretty nasty surprises

. For instance a group of Dire Rats becomes a fairly tough encounter if you swap out Alertness for Swarm Fighting (Complete Warrior).

Concerning Inspiration points. What happens if a Factotum uses one of his abilities before or after an encounter? Is he stuck with the number of points left from the last encounter? Somehow I cannot find a section covering this situation. Maybe I just overlooked it.
