I think the mechanism is nice, but it's preferable to be executed in leather to maintain a consistent look The excess ties should be handled better too..

Personally, I'm going to wrap my device in a invisible shield\bodyguardz type material and just pocket it 'nude' to maintain the slimmest possible size.

I'd probably buy a belt holster or a sleeveless clip too because I use them occasionally, but not everyday..

Leather cases (like Vaja) adds way too much bulk in my experience, even when you never put it in your pocket and they spoil way too quick for my taste (even Vaja.. bought a few of those in the past).
