2 minutes on Google found this:
http://www.allspectrum.com/store/product_info.php?products_id=28
So much for "thousands of pounds", HPS10 portable handheld oscilloscope,
on sale for $119,99.

You must have a radically different idea of what a "decent" computer is
than I do. ;-) My PC was white hot when I made it, and that only cost me
£500. (Obviously it's nearly obsolete *now*... but back when it was new,
it was pretty hyped.)

Yeah, well, that's a digital replica. I'm talking about the real
osciliscopes with the large CRT display and so forth.

Define large CRT display and give some models of "real" oscilloscopes.

You're talking about older hardware, then. A digital oscilloscope that
provides the functionality would be sufficient for many uses. We used to
have one of the CRT-based ones you're talking about in my high school
electronics lab, though - they're not all that expensive either.

The item linked has a grainy little display that isn't going to show you
a lot. Maybe that mostly doesn't matter, but I imagine for many
applications you'd need rather higher resolution than that.

The practical resolution can be controlled, since the picture can be scaled.

It's not hard to find something with higher resolution that's not
thousands of pounds.
You're getting hung up on the details of one device and missing the
larger picture that a usable device doesn't cost what you claimed.

Right. When somebody said "I have an osciliscope" I just assumed they
meant one of those really expensive once you only ever see on TV and
forgot that these days you can buy cheaper immitations, so it's not
quite so surprising.
(Heck, these days it wouldn't be too surprising if people don't just buy
some sort of probe, connect it to a PC and display the signal that way...)

So you made a bad assumption. It happens. <shrug>
