It's located on the side so it is hard to press it without causing the keyboard to slide. To make matters worse it is very flush with the body of the phone and has very little tactile feedback (it doesn't have a satisfying click). I totally solved this by downloading a free app called "No Lock". This app will eliminate the need to unlock your phone once your phone is turned on but more importantly it allows the volume buttons to wake the phone. Since the volume buttons are 1000% better than the power button this is an awesome improvement for me. The volume buttons have a reassuring click and are not so flush with the body so they are easy to use. Now I can wake the phone very easily with one hand by simply tapping either of the volume buttons. I also purchased another app (for a buck) called "Screen off". It's an app that will cause your phone to enter sleep mode by tapping an icon on screen. Between these 2 apps I NEVER have to touch that lousy power button anymore.
