The ubersexy black hardware may be slow and outdated now, but the interface that made NeXTstep so cool still lives. OPENSTEP and GNUstep implement the funtionality of NeXTSTEP. MacOS X borrows heavily from the NeXT interface. OSX implements a dock, a file manager that looks a lot like the NeXT file viewer, and Display PDF, the successor to Display PostScript. (this is hardly surprsing, considering Steve Jobs developed NeXTSTEP, and returned to Apple in time to lead OSX development) People still try to NeXTify their system to emulate the user interface of NeXTSTEP.
