OK, I maybe one of the few here to really appreciate this.
But one of the big gaping holes in Linux software has been CAD -- until now, Linux has not had anything even close to a first class CAD system. Pro/E is definitely first class, although very complicated to learn and use. The new version (Pro/E Wildfire) looks like it may be considerably easier to use, perhaps as as easy as SolidWorks. But SolidWorks doesn't seem interested at all in porting to Linux, and it doesn't seem likely that any of the other major mid-range packages (the top 4 are Pro/E, SolidWorks, Solid Edge, and Inventor, with smaller players including IronCAD, CADKey, Vx, Ashlar, etc) will be ported any time soon.
So, if PTC keeps up their pro-Linux (and Unix; they also support Sun) attitude, they'll be my choice for CAD software (and I might be in the market in a year or two). I plan on telling PTC that this a good move. (BTW, PTC does have a noxious licencing scheme tied to the CPUID but their competitors love dongles and PTC has made a number of changes that have impressed me, with Linux support being the best).
