I'm mostly with you on static methods versus singletons but it's worth mentioning that a singleton object has the advantage of being able to implement an interface, but there is no such capability for separating interface and implementation for static methods. I think static methods are OK for the same reason that not every object needs to be an implementation of an abstract interface, but you should be aware of the possibilities you are eliminating when you make that choice.
