It is justifiable with a computer,as it is a general purpose device,which you can "customise" as required.
An Oscilloscope,on the other hand,is a Test Instrument,which should be usable straight out of the box.
I'm not talking about wave gens & crap like that.
I'm referring to the fact that some devices cannot perform their most basic functions satisfactorily,so the fix is to download some kind of "bodge" in the form of a new generation of software.(And pay money for it!)
OK,that has been a satisfactory business model for Microsoft,but if I was a boss who found that the 'scope I bought at great expense didn't work,I would go elsewhere.
There are precedents in hardware stuff-- Tektronix 650 series,& Philips LDN xxx picture monitors
come to mind.
But they were just stuffups---some of the software stuff seems intentional!
