Is the Countdown display equipment at bus stops really obsolete?

When iBus was 'launched', one of the arguments justifying the cost
was that as well as being technically superior (which it most
certainly is), it would deal with the problem that spare parts were
getting increasingly difficult to obtain. *Accellerated removal
rather than repair of knackered boxes supports this, but I've yet
to see anything 'official' - either way.

Presumably removal of some also generates a supply of spares for those
remaining in use?


As I said in my other reply to Andrew, the "obsolete equipment" that
the iBus system will replace is nothing to do with the actual
Countdown dot-matrix displays - after all this is hardly specialist
equipment, it's just standard off-the-shelf stuff- the obsolete
equipment argument surely revolves around the whole beacon tracking
system on which Countdown is based. AIUI this beacon tracking system
used to form the basis of TfL's bus tracking system (see earlier posts
in this thread), but that role has now moved on to the GPS tracking
system employed in the iBus project.
