They don't wonder; they know very well. But they're stuck. Consider
oscilloscopes. Why pay for a Keysight or Tectronix or LeCroy or, God
forbid, a Rohde & Schwarz when, for the vast majority of applications, a
Rigol will give you everything you need at 1/N the cost?
The hugely expensive, overbuilt gear that we grew up with is yesterday's
news; that's why we can scarf it up so cheap on the 'bay. Lots of labs and
manufacturing facilities now consider basic gear like DSOs, SAs, DMMs,
PSUs, and sig-gens as disposable as cell phones.
I'm not sure that is a bad thing.
