Possibly there could be two streams of entry, those working via formally registered companies and the personal entries: realistically speaking, there are very few private users who realistically would benefit from more than 100 or 200MHz of bandwidth.
While it's true that speeds are continually increasing, a 500MHz scope is still a serious workhorse in any lab I've been in (except perhaps in the ones frequented by a well known LeCroy aficionado!). Easily 90% of the stuff I do could be done on the Rigol MSO1074Z I use for field work, it decodes and triggers on 50MHz SPI busses well enough for example, but I much prefer the UIs and screens on the MSO3054A and/or MSO7104B that are already set up on the bench. It is just those small minority if times where I need anything more when probing high-speed busses for signal integrity, and for that it's the big iron 54121T 20GHz sampling scope. While it would be nice to have a modern real time 20GHz scope, there are many other things ahead of that purchase!
