Serious test gear reviews now constitute a very small proportion of Dave's output. Although this is regrettable one can understand why, given his comments in various threads.
As a professional video blogger he is under constant pressure to generate content, and with all the demands on his time thorough reviews require a great deal of effort for just one video.
Dave has stated that he will only continue the EEVblog for as long as he enjoys doing it and that he and not his viewers gets to pick what he works on. Since he is his own boss there is no-one to impose deadlines and consequently there's a bunch of stuff that he never gets around to.
I would personally love him to produce a typically incisive review of the DS1054Z, or a new set of design videos, or even the long-awaited multimeter showdown, but if the price of his continued presence and enthusiasm is an occasional frustration with the slow production of more in-depth content, I am happy to pay it.
