Ok, so I've been in touch with Tech Support. My main concern with the power button not working was not being able to update firmware. Other than that, powering off is not a big deal to me, and I don't use screen lock all that often. Elliott was very helpful, and walked me through changing the firmware without the power button. Since I know I will be able to update firmware whenever new releases come out, I am content keeping my Pocket Pro, rather than sending it back. And they are going to send me a new case to replace the one that was broken when it arrived. I am very pleased with the way Astak has taken care of this.
