I received my Otterbox commuter series mineral blue case this afternoon. It is very easy to install and you can tell by the quality of the materials that they are durable. The case fits the phone very well. All buttons work well with the case on and this includes the power button. The signal strength is the same as when the case is off. The case does add a little bulk to the phone BUT I've been carrying mine around "caseless" waiting for the Otterbox to arrive. I really do not mind since I've been afraid that the phone is so thin it would drop out of my hand and get damaged. I will certainly take the Otterbox protection. With the case on, it is about the size of the IPhone 4 and it feels good in your hand.
