That's more like an Oscilloscope should look like.
First & foremost, it is a device for looking at waveforms, not reading numbers off a screen filled with clunky "graphics" just because they are "trendy".

In the screenshots that have been posted so far, I could not see that it were "wrong".

I agree.

Rigol isn't "wrong" (or showing a "bug"), they're doing what's practical.

PS: I've been away for a few weeks... did anybody ever try putting an actual AM signal into the Siglent?

Of course not. Oscilloscopes are just decorations when furnishing a lab.

(I can't find a suitable smiley after that my statement. But I guess everyone understands that kind of thing.)

Indeed.  But even plenty of modern T&M instruments weight significantly more than 10.6 kg.  I used to tell people that one of the job requirements for working as an AE in T&M was "Must be able to lift 25 kilograms."  :-DD 

I feel sorry enough for my FedEx driver that I regularly help him load and unload instruments when he comes to my house. 

A good cart is also pretty much a requirement: field T&M professionals talk about and compare carts the same way that most people do with cars or boats :)
