Yeah, I personally only ever run 32bit version of vista/7/8 on old machines that don't support 64 bit. But if I had a piece of hardware that only has 32bit drivers then I may reconsider.
The only problem with DOS software is that they did arbitrarily limit you to the amount of ram a DOS application could allocate for a while, but I think Microsoft eventually limited it.
