Hi there,
Preaching to the Quire here, I agree in the present form it’s more of a Novelty device.
I don’t see the point of the SD card on there no advantage at all over an add on one.
and LOL add it to the round display and you have TWO (well one doesn’t work, when you do that)
It’s cool that such things exists as demo though. Also some folks are having better luck with the Heatsink on the back as well as other camera models .
