The back story to this is that the DIGITAL Command Language (more or less the equivalent of an Unix shell), with its excellent filesystem-level features and the environment around it (e.g. the well-written and extremely thorough documentation) was very much light-years ahead of anything you could get on most Unix environments at the time. Going back to the Unix shell felt a bit like a step back.

FWIW, there are plenty of complaints about things other than syntax after the fifth paragraph or so, too ;).
