I thought this was a very professional video by Mr Greenberg who clearly has a good voice for this type of work, as opposed to the majority of iphone video reviewers I have heard

Leaving aside any potential issues re signal impairment and the ability to use various non-Apple accessories, what I find a bother is the actual fit and the "daylight" as Mr Greenberg mentioned. The idea of pocket "debris" having very easy access to the stainless steel surrounding band and scratching it up would require one taking out the Allen key and disassembling the whole thing on a very regular basis.
