One of my old friends recently got his station set up with Windows 8 64-bit + USB + unknown cable on a Lenovo Thinkpad. He says that everything works fine aside from NCS, and I'll be meeting him this weekend to program his car and so how well his setup runs. It seems that we're no longer bound by XP or 32-bit operating systems in general.
I have a spare Lenovo T420 that I would love to put to use in case I'm ever in a BMW again.
