Look, I'm not defending Apple...
But my Samsung candy-bar phone, which has metal all around the edge, loses bars, and has reception problems/static/breakup as well, if my hands are sweating, and I'm gripping the phone in my palm tightly. Every phone I've ever had has reacted badly to the same thing - my hands get sweaty, the phone starts to slip as a result, I squeeze the phone tighter, and I can see AND hear the reception get worse.
On the advice of a friend, I bought a $2.00 rubber back for the phone that also covers the edges. What I thought was only sweaty hands turns out to have been some condensation as well (warm hands, cold phone edge), the phone doesn't slip when my hands are damp anymore, and my reception and call quality are fine now.
So while I'm not qualified to say Apple is in the right, I can at least say it's not just iPhones that have problems when conductive surfaces are blocked by damp skin.
For what it's worth: I could never wear a watch either. In the 60s, growing up, I'd put on my little wind-up, and and eventually, inevitably, it would stop. I'd take it off for a bit...it would start ticking again. I'd wear it for a while...dead watch. Let it rest a day or two...live watch.
But eventually every one of my watches would fail permanently. Try as I might, I could never get a single one to run again. (I don't count the one I took apart, at age 8, thinking I might repair it. When I removed the back, something went "sproing" and a tiny part launched itself into oblivion. I contemplated asking my parents for help, but fortunately my sense of self-preservation kicked in, at which point I calmly snapped the back cover into place, put the watch in a drawer, and sauntered off humming nonchalantly.)
I can offer no explanation for the watch weirdness. I can, however, state quite confidently that watch repair and shag carpets are a less than optimal combination.
