I just used a fully digital oscilloscope for the first time

Are you maybe at slow time base settings? It may be that the TBS only updates things like vertical settings after a full sweep, so if you have the timebase set to say 100 ms/div, this could add to the perceived latency. The waveform update rate (number of sweeps per second) will likely be a lot slower for this scope than for an analog scope. Although more modern scopes like the Keysight scope are a lot better here, and limiting writing speed of the CRT would also limit the effective waveform update rate on analog scopes.

No, the whole thing was just slow.  Pushing a menu button, it took like 5 seconds to display a menu, changing a menu was decently fast, but that's after 10 seconds of waiting for it to display a menu.  Changing the timebase was disastrously slow, whether in the MHz or Hz range.  It was almost impossible to find the signal without overshooting first.

This isn't a scope I bought, I was just testing it to make sure it's working for someone and comparing it to my decently calibrated 2230.

It is irritating when people do that. Sometimes it is beneficial to realise that if you know how someone earns their money, you can predict what they will say.

Both HP and Tektronix made instruments based on Smalltalk, in the late 80s early 90s. Those programmers knew what they were doing.

I made a video of my TPS2024 booting up and looking at a 1kHz 1V square wave with some basic operations such as channel coupling, cursors, zoom, vertical scale, timebase, FFT and measurements.  Is the TBS1072B comparable or slower?

Wow is it a pain in the ass to use compared to my analog/solid state 2230.

I just used a bicycle for the first time. And boy does it suck, compared to walking. So wobbly! You can't even stand still without falling over! And don't get me started about walking backwards... I'm giving up on this thing, I have certainly had enough.
