Did Theo Gray's definitive Mac front-end pre- or post-date Mathematica
on NeXT?
The Mac version certainly out-sold it.
  Modern day MacOS X
 is heavily influenced by NeXTStep and it's Objective-C development
 environment, as is iOS. 
More than "influenced" - OS X and iOS, a lot of the widgets, utilities,
file formats, protocols and supporting applications, derive directly
 from that code.

  WebObjects was a fairly popular application
 framework in the late 90's and early 2000's - I know of a few major websites
 that used to run it.
 I'd say NeXT was relatively successful, in that it was used to create
 popular products and had a direct impact on later products.
