How much slower? Pro/Engineer runs some 85% slower. UGS NX runs 98% slower. Maybe that's why PTC wasn't whooping up Vista at the media event earlier this month.
As can be expected elsewhere, SolidWorks also notes that some features stop working with Vista, such as MoldflowXpress and MDT translator.
This dismal performance explains why Microsoft's half-billion-dollar marketing campaign consists of feel-good expressions -- instead of facts -- like the Gatesian comment at yesterday's launch event: "This 'wow' thing is a great way of describing what we've got here."
It's all about the wow. Wow. Perhaps 'wow' is an abbreviation for "worse or worser."
I don't want wow. I don't want a shiny user interface that sucks CPU cycles away from my apps doing real work in earning me a living. I don't want to pay $399 for worse.
As Wendys used to ask in the 80s, "Where's the beef?"
