I hate to inform you a 2240 would be considered as a dinosaur today.
A modern and compact DSO has far more functionality.
But not delayed sweep, so most modern DSOs cannot for instance measure the timing difference between adjacent pulse per second pulses at their best resolution. Doing so would require upwards of a 1 Gigasample record length. An old DSO only requires a 32 bit counter. Modern high end DSOs get around this limitation with segmented memory.
I would agree that analog and older digital storage oscilloscopes are long obsolete, but that does not make every "modern" DSO better for every application. Some modern instruments are pretty horrid.
My digital and analog scopes are about the same size.
Since my most used DSO is a Tektronix 2232, my most used digital and analog oscilloscopes are exactly the same size.
