If it is absolute then you should be able to define yes?

Of course, like with cars, classes are not always sharply defined.
Yet there is a consensus about the main requirements for the various scope classes, mainly bandwidth, probe interface, math & measurements, available applications and software platform.
In this case it's quite simple and a single criterion is sufficient to know where to put the SDS6000. Above mid-range there is high-end. And today's high-end scopes are DSOs running on a PC platform. I'm not aware of a single high-end scope running an embedded platform. On the other hand, there are some upper midrange scopes running on a PC platform.
Now that it is clear that the SDS6000 isn't a high-end scope, how can we know it isn't just an entry level scope? Well, the answer shouldn't be hard either. 2 GHz bandwidth, active probe interface, Eye diagram and jitter measurement applications - all these are dead giveaways that this is not entry level anymore.

How can it be absolute if the definition is not sharp? That is plainly contradictory. Mid-range is relative (changes depending on competition/market/pricing) and not absolute.
I'm not disagreeing with any conclusion you come to about the SDS6000 because there are no agreed definitions. To say high end requires PC platform, but at the same time that is required but not sufficient such that mid range may or may not have that or any specific bandwidth/features/etc just proves the point. There is no agreement or widespread understanding/definition of low-end mid-range or high-end.

They would call this "mid-range" even today. I don't see why these things should have changed during the past 12 years.

40GS/s and runs Windows, yet mid-range? other people would disagree, particularly 12 years ago as that sort of front end performance used to be limited to very few instruments/manufacturers. People can add these labels and categories all they like, but it's still mostly meaningless.
Fungus:
"Mid range" varies by brand.
Most brands have a lineup with 1000-series, a 2000-series, a 3000 series ... , an 8000 series, etc.
A 4000-series Rigol is a "mid range Rigol" but it won't be as powerful or in the same price bracket as a "mid-range Lecroy".
Similarly, an "entry-level" 4-channel R&S is going to be much better (and more expensive) than an "entry level" Rigol DS1054Z.

Oh yes - I've just learnt that.

You can disagree with LeCroy as much as you like. Possibly even 12 years ago, 4 GHz max. bandwidth was just not enough for the "high end" label, even though all other requirements for "high end" (for which there is no widespread understanding) would be met.
Btw, the fact that very few instruments/manufacturers are able to deliver top notch performance hasn't changed either. This is the whole reason why up to now, only these few companies are able to offer high-end gear (where there is no widespread understanding).
Now that even our top expert has chimed in and educates us that the Rigol 4000 simple scope is midrange, I give up and will stop derailing this thread.
All I wanted was to make it clear that Siglent does have a midrange scope (where there is no widespread understanding) with HDMI.
KungFuJosh:
The recent activity in this thread gave me a great idea for a band name: "The Pedantic Semantics." :popcorn:
Whitefoot:
The Owon SDS7102V is 100MHz two channel with VGA output. About $400 new. The VGA is optional, indicated by the V in the model nr.
VGA output is 800 X 600 pixel, same as the scope screen. This is good enough for a VGA monitor, but I don't know how it would look projected.
