Neat bit of kit, I find it interesting the case has much the same footprint/style as some cheap HP desktops.
Despite what some have said, the cost looks reasonable considering all the different instruments in one unit.
I really doubt you could buy a DSO, waveform generator, PSU, and the IO stuff as separate devices for the same cash.
Certainly wouldn't get the advantage of a single PC/tablet control panel.
I could see this being useful for space constrained QA benches.
