Well, since Darwin makes up the (open source) foundation (NOT to be 
confused with the foundation of Cocoa or GNUstep) of Mac OS X there will 
hardly be any driver problems with Darwin on a PowerBook. Remember, Darwin 
is mainly Mac OS X minus the GUI and some other fancy stuff. However, I 
would not recommend it as the base for GNUstep yet if you want to have a 
well tested system. Although the GNUstep base appears to work on Darwin if 
used with the GNU ObjC runtime, IMHO nobody has tried to compile or use 
the GNUstep GUI on Darwin yet. 

I would go for some sort of Linux/PPC (Yellow Dog, SuSE) for using 
GNUstep. One issue in this type of setup is the difficulty of data 
exchange between Linux and Mac OS X. Linux does not support HFS+ (main 
file system of Mac OS X) and there are no Kernel Extensions for Mac OS X 
that support some sort of a Linux filesystem (wether it be ext2, 3 or some 
journaling type). The only solution so far seems to be to use HFS (this is 
the old Mac filesystem, it limits you to filenames no longer than 32 
characters) or, for the brave of heart, even some sort of Windows 
filesystem, which should be supported properly by both Linux and Mac OS X.

The quality of workmanship of a PowerBook is classes better than of an al 
cheapo PC Laptop. You get far more battery life on a PowerBook. You get 
integrated WLAN (no antennas to break of), you get bootable firewire, 
which is good if you have external 2,5 inch poket drives. Firewire comes 
also in the 6 pin flavor, which means that you don't have to carry 
powersupplies for your external gadgets. For the other connectors (look at 
http://www.apple.com/powerbook/specs.html) I don't have a comparison to PC 
hardware since it differs to much from PC laptop to PC laptop. As a rule 
of thumb I would say if you go featurewise for an equaly equipped brand PC 
laptop, you'll pay about the same ammount of money.

And you'll get Jagwire ;-) for free and not those - broken by design - 
Windows variants.
