The State pattern is very useful, it's just hard to spot, and at the beginning a little hard to understand. On this podcast we cover the state pattern with a specific example of its use, plus tips on how to spot when to use it (really that's the hardest part of the state pattern). Check this podcast out, and add another pattern to your toolkit!
