They have great appeal for people who think their computer is a do-anything
tool. I think they are a waste of time and money. Putting a sensitive high
frequency preamp inside a computer? Yeah, great idea. Pointing and clicking
on virtual knobs? Oh so wonderful. Portability? Get an old-fashioned scope
cart and now you're talking!

I think it's doable, but only if you pay more than for the equivalent
standalone unit. Otherwise it's a bad compromise.

Cheers,

Bob

Hey, what could be cooler, for us technogeeknerdsliderulehacksters?
The wave of the future? Anyone interested should do searches on
"ubiquitous computing", "invisible computer", "emerging technologies",
"palm computing", "sensor-based computing", "sensor webs", on and on.

Or alternately, put the computer inside the amp. See "The Invisible
Computer" by Donald A. Norman, and "When Things Start to Think" by
Neil Gershenfeld - plus just about anything created by the wild and
crazy guys at the MIT Media Lab.

Well, I do hate Apple/M$ GUIs, too. But also see "The Design of
Everyday Things" and other books by Donald A. Norman.

Hey, I do this "now" with my scope, logic analyzer, counter,
function generator, PIC programmer, and ICE. Then I decided the
cart needed a motor plus a special device for climbing stairs,
then a video cam for remote viewing, and finally an RC control
unit for operation in hostile environments. Unfortunately, the
solar cells wouldn't keep the 16 lead-acid batteries charged
for very long :).

And this coming from a guy who's already been there and done that
too:
