the earliest I recall was when galaxy s2 came out and tooted at the thinnest on market. Of course I thought it was retarded, since the camera is sticking way out.
I remember thinking the thin craze was stupid back in the original RAZR days (flip-phone razr).I just think it makes it hard to hold.
I miss the old rotary phones.Nate
I don't really see the attraction of ultra-thin phones either. What I want is a moderately-smart phone with a small screen (3.5" diagonal or smaller). I can't find anything like that, so I'm still plugging away with my LG Optimus S, which can just barely handle the most basic apps. Some day soon I'll have to give up and upgrade to a newer (larger) phone, but I'm holding off as long as possible.
At some point the size of a phone has to start being inconvenient. I would almost prefer 2 devices like a smaller more robust, longer lasting phone and a complementary tablet or some other type of larger screen interface for surf/media etc.
