"I can not remember a single instance of missing wired NIC drivers on install"

Were you pre-installing NIC drivers with your images? That'd be a good reason for the high success rate.

It might also have to do with specific manufacturers/vendors. Most of my installations were on Dells; it's possible HP or Lenovo stuck with chipsets that Windows properly supported out-of-the-box. Linux worked fine in all cases.
