There are 66+ licensees...obviously some companies out their are interested in NeWS. I really despise ignorance...so I will also mention that NeWS is the basis for Silicon Graphics windows system (that's right...not X11), it also is the basis for Raster Technologies products, it also was available on the Mac before X and on OS/2 before PM...further NeWS is a SUPERSET of Postscript...it understands processes, windows, events, etc. > X issweeping it aside even if, arguably, X isn't addressing quite the same > problem as NeWS. (Hell, corporate deceision makers don't want to be > bothered with little details like that.) I have a healthy respect for X11 but with the exception of the networking it is the same old ten (or more) year old techology ... it is no REAL breakthrough...X is a toy when compared technically with NeWS...(you can emulate X from NeWS...the reverse is not possible) As for X sweeping NeWS aside...wait....System V Releas 4 Unix will contain X11/NeWS ... so lucky Sys5.4 users will be able to have BOTH... running under ONE user interface OPEN LOOK. When we have X and NeWS on the same machine...my money is on people recognizing the sheer technical advantages of NeWS and the weakness and limitations of X/Display Postscript. However, why worry ... System V Release 4 will have a merged X11/NeWS which will allow users to run both types of windows in a harmonious fashion. Hopefully you now understand your statement about NeWS being nowhere but Sun (and the 66+ others) makes even less sense since it will be part of Unix. :-) > > PostScript, on the other hand, is a de-facto standard, and to me, Display Again complete SHEER IGNORANCE. NeWS IS a Postscript *superset* - they send you Adobe's Postscript books so you can learn NeWS!!!!! I routinely display Transcript (another Adobe product) produced Postscript in NeWS' psview which allow you to view postscript files. So you are CORRECT in your own perverse way...Postscript is the de-facto standard...but NeWS not only groks Postscript but does Postscript windows, networking, events, processes, canvases, etc... Adobe DP does not. > PostScript looks to me like an obvious next step (groan), provided that Display Postscript is a subset of NeWS, it depends on the native windows system and has a substantial less features...no dynamically extensible server (since X11 has none)...no variable path windows (like circular, triangular), etceter etcetera etcetera Now for the answer to the original question : I really doubt Job could bring himself to endorse NeWS ... he then couldn't bring himself to endorse X...marketing reasons underlies both decisions... (Jobs is bright at hyping, marketing and organizing and synthesizing ideas) ... Not using X or NeWS doesn't make the machine any less creative and interesting ... > Dominic Dunlop I am sorry for the flame...but next time you post facts ... do a little research first. X/Display Postscript has alot of potential...but quite simply (because NeWS is a superset of DP) X/NeWS has alot more potential. -------------- My opinions are my own...and i type them on a Sun running NeWS :-) and soon it will be running X11/NeWS ... and if I want to run a NeWS window I can do that ... and if I want to run an X11 window I will be able do that to... and if I want to cut and paste from an X window to a NeWS window I will be able to do that ... and if I want Postscript I have a postscript (NeWS) shell and postscript viewer ... and I will have an X toolkit and a NeWS toolkit for development ... and if I want to have X do what NeWS does ...sigh...well then I CAN'T DO THAT. (sorry for being obnoxious... but consider it an education).
