Sorry for top-posting. You are simply wrong about it being a print unit. It is simply a unit where 72 points fit into an inch. Nothing more, nothing less. It can be translated into screen pixels or dots of a printer.

Hey I'm all for being wrong but... on smartphones with 300dpi pitch they do pixel doubling so 12px fonts are made twice as big to compensate. px's have the additional benefit of allowing you to line up fonts with images or other elements easily. Perhaps pt's could work but it would be non-standard for web work, why use a print unit to the web?
