Why do you think there aren't more "good" USB oscilloscopes?

Is hardly a USB scope. :P
Instead it's a remote acquisition system with 4 or 8 channels and multiple units can be remotely linked and synced for up to 512 channels.
It might look like a USB scope but that's all as you connect a keyboard, mouse, mains and a display to it however it can also mimic a USB scope in that you can use a PC to drive it like any scope with webserver capability.

That's the kind of thing you get when you are running some large scale scientific experiemnt to collect huge numbers of channels of data. Quite niche.

Or production monitoring/control applications.
That they can be scattered about linked by LAN and also synced with the purpose built SYNC64 module and able to be controlled from a single location makes for a darn powerful system with each 4ch set a headless SDS6000A DSO with all its 5 GSa/s per channel capability but minus a touch display like the scope has.

Is it a scope? Yes.
Can it be used from a PC over a standard computer interface? Yes (only on ethernet? no IP serving over USB?).
Sure seems to be what the OP was asking about:

The cost savings of using PC hardware for control and display would surely allow such gear to be price competitive?

Yep so it can be a computer connected scope, with the same front end and processing of its "fully equipped" version. Exactly what the OP was asking about!

USB scopes are a really niche market item. The computer side with the display and whatnot is so cheap these days that there is very little saved in going with the USB form factor that requires you to drag around a computer and deal with cumbersome controls. For around the same price you can get a standalone instrument. I've used USB TE before and have never been impressed, it's less convenient and offers few advantages. Back in the day the promise was cheaper gear by not having to duplicate the processor and display and such but it never really lived up to that promise IMO.

Speaking for myself, it's not that I'm trying to save a few measly dollars on the screen or power supply or whatever. It's that when I'm called out to a job I already have my laptop with me with a nice big screen and the necessary processing power to run a scope/sig gen/etc, as well as a few bags of tools and test leads and stuff. Carrying less gear helps, especially when parking sucks, there are a million stairs or it's a dodgy area. And it's not just that it saves lugging one scope- it also saves me needing to lug a signal generator, and also an isolation transformer in some cases. Which also means I don't need a power board, extension cables, etc... It all adds up.
