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.

Even better...
A Scope with a Gpib/Rs-232/usb interface so you
have "both" the instrument itself independent
of any pc...but if you ever need it - you can
record them to PC anytime because of the interface.

In fact...most of my standalone instruments have this.
