newbie looking for books on GNUstep/Cocoa

[Ralph Moeritz]

Hi everyone,

I'm a newbie to Cocoa/GNUstep, but already proficient in Objective-C.
Does anyone know of any books on Cocoa that target programmers
already proficient in ObjC? I would hate to buy a 400 page book, only to
find that the first 200 pages or so are useless to me.  How much of the 
information
covered is Cocoa specific (ie. not relevant to GNUstep)? I would download
Apple's Cocoa reference, but the PDF file is 22Mb, which is too much for 
my old analog line to handle :-(

I've noticed that some header files have been moved from AppKit to
GNUstepGUI, why is this, and does it cause compatability problems with
Cocoa?

Also, are there any plans to integrate Gorm & Renaissance ala 
Glade & libGlade? I would hate to have to choose...

Thanks,
Ralph Moeritz
