It gave me an quick introduction to what it's all about by going through 
the tutorial and the manual. A teacher of a friend once said "you can 
only learn things you already know" which I later have come to realize 
how true that was. I have a grasp of it now so I know [a bit more] what 
to look for in the Intel docs and what it can do. Ie the same reason 
people buy O'Reilly books, to get a grasp, and then it's easier to read 
the RFCs.

But I don't think I'll use the gui for actual coding. Even if the 
graphical timing thing did seem useful.
