MathType looks decent for maths (and I assume engineering). I can see the appeal of the WYSIWYG, though I don't really see how learning a bunch of shortcuts is materially different from learning the Latex commands. Nevertheless, it still doesn't have a bunch of the symbols I need, which was my point about smaller domains. I'm glad it works for you, but given the advantage seems to me marginal and it offers no options for extensibility, I'm still unconvinced that we're at or even close to a stage where Latex has no place in writing documents.
