Not bad. A little virtual visual infinity going on as well. Cool.
So mechanically, does it seem to be sound? Does it look like it could over-stress the microSD port? One thing... I'm not sure I'm diggin the keychain "clasp" or "hook".
Do you imagine yourself using this constantly connected to the phone?
For me, for the few times I might want to bring content with me, I imagine the internal storage to be fine. However, I could see putting lots of audio / video / pictures on an external storage device. If I'm home, I think I might prefer a "wireless" solution.
If very infrequently used, I wouldn't mind something like this - perhaps a bigger OTG USB port and the use of a conventional stick... It would be very cool if some company produced a product where it took up the width and thickness of the device... perhaps even a protective case that integrated something?
Can you charge with the thing plugged in, or does it take over the port?
