Can someone point out what is the difference? And what for do we actually pay so much money, when supporting the iPhone with our hard work?

I've figured out how to use the NSBezierPath class to draw shapes in the drawRect function of my custom view class, however I can't seem to figure out how to draw text.

I'm just starting to learn Objective-C using GNUstep on Windows and I'm wondering what type of debugging options are available? I'm using make to compile and link the code, but once I run the app there doesn't appear to be a way to step through code and inspect variables, the call stack or whatever. Now this isn't the end of the world if...
