Personally I prefer the factory method approach, a la [NSArray
array] etc:
Note that factory class methods typically also return id for the
same reason that init methods return id (NSArray, NSString, et.c.).
This in contrast to shared instances that are strongly typed
(NSFileManager, NSHost, NSNull, et.c.).
Moreover, a problem with using the "factory method approach" is that
they return autoreleased objects.
If you have a particular need to be concerned about performance (as
you might especially in a resource-constrained environment), it is
generally a Good Thing to avoid autorelease and instead use alloc/
release directly.
