I agree. However, the charm of a PC-based instrument ist the
availabilitiy of the data on the PC for further processing.
One way to get close to this e.g. with a stand-alone scope is
to photograph the screen with a digital camera and to work on
with the jpg file.
Or to combine a real good digitizer with a cheap old scope.
