"But at the same time, show me a large scale project done in PHP, and I'll show you a large scale project that would have been better off in Python."

Agreed, and..

Show me a large scale project done in PHP, and I'll show you a large scale project that has other code embedded, like C (or any C variant).

Remember the movie Red Planet (with Val Kilmer in 2002)? The stranded astronauts were out walking the land and Val whips out the tube shaped computer and pulls the screen out like its an Old Testament scroll. Its a computer screen. Think about having one that you mount like a projector screen, only now you won't need the projector.

The questions from people who don't fathom what a new technology could be used for always precede massive adoption: "Why would we need to carry our phones in our car?", "Why would anyone want to have music on a device you have to carry around?".

Know anyone who does NOT want a cell phone? Know anybody that does NOT have or want an iPod/MP3 player?
