They still make high-end Tektronix 2465 cotemporaries as well.

Analog and digital each have their advantage. What you posted isn't a surprise at all. Digital equipment are much cheaper with hard goods than analog counter part.
With a purchase of a set of encyclopedia, you're clearly paying a good amount for the intellectual property. A set of encyclopedias on high quality paper in full color costs thousands of times more than pressing a few DVDs. Physically, the DVD needs to be built to close enough tolerance to ensure readability and perform within acceptable vibration levels, but overwhelming portion of the cost goes to the contents. For instruments, a good portion of list price goes to dealer network as these instruments are sold through traditional business-to-business sales rep network who does everything including hand holding for end users.
There are some parts that still require very close tolerance to actually work and can't be BS'd much, but for the most part, digital instruments can get away with roughening it in and BSing it using calibration constants. The materials used still need to be very stable in long term and critical components must have very low temperature coefficients, or have a very predictable coefficient.
A high accuracy glass thermometer requires a very accurate bore diameter to maintain linearity. A cheap one would be marked at low, and high and marked evenly through out, but if the material is the same, then it is just as precise. 5C reading might mean 4.5C and 10C might mean 10.2C, but it is consistent. Inscribing the glass with lines where each line must corresponds to a very high level of accuracy is a costly process. If it was to use a scanner array like optical device to read the incision where the mercury is, it can be BSed numerically by simply comparing to a reference thermometer. So, reference thermometer and this thermometer is heated and cooled side by side until they both stabilize. If reference reads 28.0C, it marks that pixel location as 28.0C.
You don't adjust the circuit. The digital processing reports the pixel location of where the mercury was seen and this pixel location is translated into value by multiplying it with a calibration constant.
In analog circuits, proper true gain adjustments is important so that symmetric AC do not look asymmetrical.
In analog driven digital meters, the analog circuits are adjusted to reflect proper reading on the digital display. In digital setup, you don't do anything with the circuit, but use calibration constants in EEPROM to absorb the slop.
An analog scope literally have dozens and dozens of potentiometers and take many hours to adjust. However, with a service manual and sources, you can do it.
A digital scope and automated calibration equipment talk to each other under the direction of program and quickly bust through the calibration routine. The ability to access almost every function available on front panel through the interface without touching the switch is more important for automatic production. If you need to service it later on, the constants in EEPROM are not self explanatory and you can't do anything about it and you're at the mercy of the manufacturer.
