I would be interested in seeing this one in action too.
I liked the Seidio model and used one for my 8125, but I found it a bit awkward getting it in and out of the holster, especially while seated and a few times I almost dropped it while trying to get it released.
I always thought a release mechanism which worked side to side rather then top to bottom would be easier to manipulate. I'd also like one that could be used with the phone facing in or out.
