I haven't read the Fedora book, so this may be covered in it....but I think a book designed to encourage users to switch needs to explain the equivelant programs in linux that replace/upgrade the functionality of their windows variants.
For instance, explaining the programs, how to use them, how to configure them, etc.
Ex:
Gaim vs. AIM
OpenOffice.org vs. MS Office
Mozilla vs. IE6
Evolution vs. Outlook
GTK-Gnutella vs. Kazaa and other P2P
Gimp 2 vs. Photoshop
Xine/Mplayer vs. WMP9
solitaire vs. mahjongg
And for those applications that have no equivelent, the use of Wine, or Crossover Office.
The 2 main excuses I hear about not switching to Linux are gaming and Photoshop. With the standard version of Crossover Office now priced as low as $43 (approx), and PS7 being a supported program (which I can tell you from experience runs without a hitch, Photoshop is no longer a legitimate reason not to switch to Linux.
The cost of Crossover Office is far less than the cost of an "upgrade" to Win2KPro or WinXPPro, and the speed, stability, and security of Linux far outweighs the hassle of learning a new operating system and file system structure.
