Summary:  Classes with only one instance

Original Submission:  I have the following proposal to change classes with only 
one instance e.g. ScreenManager as follows (an example):
 
class InstanceClass
{
public:
 int x;
 int y;
 
 static InstanceClass instance;
 
 InstanceClass() : x(3), y(4) { }
 ~InstanceClass()
 {
  printf("cleaning up\n");
 }
};
 
InstanceClass InstanceClass::instance;

int main(int argc, char* argv[])
{
 printf("%d %d \n", InstanceClass::instance.x, InstanceClass::instance.y);
 return 0;
}
 
 
The advantages are:
- No more need to implement init/deinit functions: the object is automatically 
destroyed at program exit
- A direct object -> (slightly) better performance
 
I'm very curious what your opinion is.
This compiles under gcc and VC++
