So I headed to the classroom with my brand new MacBook Pro. It's a wonderfull laptop, but again the good developers from Mac had a surprise in the sleeve.
I could not use the projector!
Of course you have to buy new wires in order to do something as mundane as showing your screen to a class on a MacBook Pro. It is ok to use whatever slugs Mac fancys, but it is not ok that we have to buy new connectors every time we buy a new Mac!
Well ... on a Mac you're always the creative guy. I had to use a whiteboard, and the students had to watch the code samples on my Github repos on their own devices.
