I miss YellowBox (OpenSTEP, NeXTStep, Cocoa whatever you call it for Windows). I still have installed on my Windows XP from the last Objective-C based WebObjects - 4.5.2, but can't redistribute apps with it. It came with built in Sampler, one was able to debug with Visual Studio the compiled executables (there was a converter that took the dwarf debug info and converted it CV (CodeView) compatible one for Visual Studio). The apps looked natively on Windows (unlike GNUStep), much like Cocotron, but you were able to develop them on the system. That to be said, Apple's OS and the underlying Foundation/AppKit/UIKit are truly hameleonic - I'm sure they can migrate easily to new platforms.
