I'm going naked on mine. Going into a leather pouch lined with soft microfiber lining. Nothing beats naked. I used to swear by SPs, I prefer naked now.

Did a quick and dirty 3DMark benchmark on mine, 16165 points. Better than my Nvidia Shield. And both can play games properly with the Shield has it its controller while the Z1 connects properly with PS3 controller.

Tested and got used to using the Z1 and QX100. The default settings when both are connected for the first time is to have the pictures shared between both the Z1 and QX100, resulting in picture files being taken transferred to both into the memory card inside the QX100 and wirelessly via WiFi to the memory card inside Z1. The end result? The phone has to wait for the photos to be transferred resulting in 1-2s of wait. This may not be ideal to rapid fire shooters and spur-of-the-moment shooting sessions. To remedy this, change the settings to only save the original 18MPx file into the memory card inside the QX100, and choose don't transfer to the Z1. That way, pic snaps are instantaneous, mirroring a regular point-and-shoot. If you choose to, you can transfer wirelessly the pictures residing in the memory card inside the QX100 to the Z1 via the PlayMemories Mobile app.
Image quality-wise from the bare naked eyes, is virtually the same as my Sony RX100 Mark 2.

Three ways to zoom the QX100. One, using the touchscreen slider on Z1 when connected. Two, using the physical slider on the side of the QX100. Three, using the circular control ring around the lens. Touchscreen and slider is kinda juddery, but using the control ring it is smoother.

Took me a while to figure it out the PlayMemories Mobile app. There are no manuals for this app. To change shooting mode, tap on the mode symbol. It is defaulted to Superior Auto. This mode does not allow any manual settings, which at first made me confused on where to access aperture, exposure, white balance settings, etc. switch to Program Auto or Manual, and those settings are now available.

The possibilities are endless with the QX100. I see uses like recording videos or taking pictures remotely as finally being possible. Spy shots as well. Just don't use this to shoot upskirts shots.
