I'm going to create a phone that has all the bells and whistles. It's going to look all high-tech with it's digital display and even require an ethernet port instead of a phone line. It'll will have all the features that anyone might need, except one. Even though I'm going to put a speaker on it for speaker phone, I'm not going to add a microphone. I mean, why would people actually want to talk during a conversation in which they are using speaker phone? Isn't it way more convenient to have to turn the speaker phone off and use the headset every time one wants to communicate with the person on the other end of the line? Surely, if you are using speaker phone, it's not because you have a couple people in your office who would like to participate in the conversation, it's just to listen in on a monolog being delivered by someone far away. And what better way to get close to your colleagues than a game of "Pass the Headset, Tell Me When To Hit The Button"?
Wait, what? Cisco already made that phone? Oh right, it's the one on my desk. I knew I got that fucking brilliant idea from somewhere.
