...My service job many years ago had a CRO as a standard piece of test gear, not so now. Either service industries have dried up or the equipment is now digital with little or no scope requirement for adjustments....The gear I work on now has no application for scope measurements, it self calibrates or is locked down. If it fails to meet spec, there is no adjustment, modules are swapped or binned. ...

It's probably cheaper to keep desoldering and reselling the chips and stripping all the gold out of the PCBs like they are doing now. If you've ever spent any significant amount of time trying to troubleshoot and fix random failures (not all the same failure) in any piece of electronics (even the ones you have all the schematics for) that is incredibly time consuming and not economical. Not much return there.There probably aren't many chips in modern high end scopes that you could even salvage since a lot of the work is in custom silicon.
Actually, judging by the DP832 and DS1054Z, I believe Rigol's current design trend is to make things that look more like they belong on a shelf at Toys"R"Us rather than on a lab bench.

Let's develop a whole series of front covers like the nokia 5110.And sell other backgrounds and color themes for the display :-)

They look as pretty and as colourful as each other.
