Certainly cuts both ways. That said, my personal experience is somewhat opposite of yours. I worked at a:

    * Printer manufacturer (TC def: non-tech). Software is at R&D.
    * Chip machine maker (TC def: non-tech). Software is at R&D.
    * Online marketing consultancy (TC def: tech). Software is with the IT department.

All that said, people at the non-software technology firms listed above do tend to have a certain disdain for software, mostly driven by a complete misunderstanding of what kind of complexity software people actually deal with. After all, all the physicists and mechanical engineers have written some while loops too, in their days. How difficult can it be? Anyone who understands if and while can write software, right? :-)

Still, at least they considered software technology, too, and not "IT services".
