Not used them so not tested but is it possible to port over mobile phone gps to a pc? thereby getting round the 100% cpu issue experienced on the tomtom emulation.
either windows mobile or symbian versions
lots available inc route 66 or tomtom mobile 5 or Navicore (recently released over here and very successful in other countries from press releases.)
they work with normal gps mouses so must be a way to emulate.
