My opinion, not actually having one, is that it is a great idea but might not be an ideal solution (at least for me). I have my Bold set to display the flip clock when charging so that I have a bedside clock. This holster doesn't put the device to sleep, so if I were to use it, my Bold would display the clock while in the holster because it would be charging. That's not how I would like it to work, but this is not a fault of the holster, and the Bold is behaving as expected.
It also seems a bit thick for my preferences. My choice would be the extended battery over this holster (but then I don't have that either).

"Wow" is now overused. Therefore, I will use "Magic bananas" instead.
