Roy, I don't think you stepped in it. You just grazed it with your foot.
Re:
"Not necessarily because it is the most powerful, the most widely used or even because we like it, but because it doesn't require all the workarounds necessary by several market leading programs (including but not limited to AutoCAD & Illustrator)."
I see it differently. The hardware manufacturers are also responsible for developing the drivers that go with. The "workarounds" are needed by third party programs (ie. AutoCAD, AI) that adhere to industry printing standards (ie. Postscript). The hardware manufacturers should fix their drivers and thus remove the need for "workarounds". I'd say the purveyers are only recommending what the manufacturers recommend themselves.
I design, engineer and program all sorts of things.
Oh, and I use Adobe Illustrator with an Epilog Mini.
