I was wondering how many of you actually use the green answer key... Since I usually don't. When you dial a number, it's much closer and faster to tap the shown name, or to tap the on-screen "call" (if you don't have the number in people app) then to go all the way to a physical button. When you're answering a call, you mostly swipe the on-screen lock bar to answer. At least I do. So, the only usage of "the green key" for me, is when I'm sending MMI codes (checking data plan). What about you?
