To diverge very briefly, Beta is pretty much out of the *consumer* market,
but it still has a significant presence in the professional market, for
pieces of equipment priced in the range of thousands to tens of thousands
of dollars. I saw an editing player a few weeks ago which can hold some kind
of monster cassette (presumably for longer play time) as well as the smaller
cassette. That system has quality and features, but not a consumer-level 
*price*.

It's arbitrary from a technical sense, but it would still be nice to have
a recommendation one way or the other, to reduce duplication of effort.
In some other fields, an arbitrary decision *must* be made for technical
or safety reasons, for instance the use of the small slot for the "hot"
conductor in US electrical outlets. For that matter, the dimensions of a
5-perf mount are somewhat arbitrary, but following a standard is advisable
to assure compatibility.

I agree that the stereo/computer standards appear to be more critical
from a practical viewpoint.
