level. I've only used OSX a little bit, but I'd be interested
to hear from anyone who has used both about what Apple
did to NeXTStep to turn it into OSX.

Hmm. Well, I never used NeXTStep or OpenStep by itself, but
I did pal around with future NeXTSteppers in grad school and
I did recently complete Aaron Hillegass' "Cocoa Programming
with MacOS X" (great book for us newbies by the way).

From what I can tell, the differences are:
- obvious ones: PowerPC native, re-branded as the "Cocoa" framework
- Display Postscript replaced with Display PDF
- addition of (deprecated) Java Bridge to allow Java apps
to use Cocoa
- XML support; used very heavily in system config files

What's still the same is more interesting:
- "NS" prefix on all classes
- Objective-C instead of [your favorite popular OO language here ]
- Mach kernel (pre-Jaguar) still version 3.2 IIRC

Anyone else care to add/remove/debate/whine ?

Cheers,
