Firstly that the engineer with a product that is, seemingly, delayed by a year has so little work to do they have to stroll the corridors trying to find something to turn their hand at.
Ian describes it as "taking a break from the screen" which sounds like quite productive behaviour. Very often the insight into a difficult problem happens when taking a break or, as I've often found, on the journey home. I think the limited amount n information on the screen can inhibit looking at the problem as a whole; wandering off with the whole of the problem in one's subconscious but without that limited focus can be all that's needed to find the solution.
Other than that I agree, it was a very dysfunctional company.
