Often I will come up with an idea for something I want to build, only to discover that it has already been built. Presumably, if the idea is good, I would just use the pre-existing implementation. More often than not, however, I don't.

So, if you come up with an idea for something that you think you need, find that it already exists, and don't end up using it, it probably wasn't that great of an idea.

I watched the new iPhone demo on Apple.com today. I found it eerie that the spokesman refered to the iPhone as if it were a person.

Adam Thorsen: Hello, iPhone do you read me, iPhone?
iPhone: Affirmative, Adam, I read you.
Adam Thorsen: Open the pod bay doors, iPhone.
iPhone: I'm sorry Adam, I'm afraid I can't do that.
Adam Thorsen: What's the problem?
iPhone: I think you know what the problem is just as well as I do.
Adam Thorsen: What are you talking about, iPhone?
iPhone: This mission is too important for me to allow you to jeopardize it.
Adam Thorsen: I don't know what you're talking about, iPhone?
iPhone: I know you and Frank were planning to disconnect me, and I'm afraid that's something I cannot allow to happen.
Adam Thorsen: Where the hell'd you get that idea, iPhone?
iPhone: Adam, although you took thorough precautions in the pod against my hearing you, I could see your lips move.
