As with so many things, you don't really NEED them. Singletons are (or
are often abused as) global variables: You never know when these objects
are constructed, and have very little control over it. When it comes to
unit testing, they can be a real pain in, you know where.
The main problem is that they do not abide the Law of Demeter: they do
not come in through the interface of your objects.
Willem - could you explain that last sentence, please?
