I loved the F3 I had, and most people thought I was crazy when I used it. Alas, it was crippled by pretty terrible antenna design, and would drop calls all over regardless of coverage. The SMS capability was almost as entertaining to decipher as Google Voice voicemail transcriptions. One argument for slightly thicker devices is ergonomics. I found the F3 to be slightly tiring to hold on to, and I feel similarly about the Nexus 5 I currently use. At some point, thin becomes too thin and I feel like I am pinching the device instead of holding it comfortably. Obviously, these are subjective elements, but worth considering.
