Active versus passive DisplayPort adapters
A while ago I bought a new laptop, and it has a mini DisplayPort to connect to a monitor. The mini DisplayPort rose to fame thanks to Apple users: when doing a presentation they always ask “does anyone have a spare adapter so I can connect to the projector?”.

I’m one of those people now: my Dell laptop (with factory-installed Ubuntu!) has a mini DisplayPort. When I ordered, I could add an adapter, to connect to my VGA monitor. But why pay around €35 for an adapter when I saw them elsewhere for more like €15. With no apparents difference.
