I've been looking for laptops with S/PDIF (or Toslink) connections to use with my Hi-Fi setup, but the search is becoming very difficult! I'm not limiting myself to brand new either, and would be very happy with a model that is from 2007 or newer, providing it has at least a dual core processor and a minimum 2GB RAM.
