A look at an original iPhone prototype

If anything a big board like this is one way to ensure it's not easy to steal.

The on-board (pun intended) documentation - "Do not connect battery without removing J49", etc - is pretty neat too. Is this something that's fairly standard in the industry?

Yes. Such notes are standard for development hardware.

Items 6.14.* on http://pcbchecklist.com gives an overview of what is typical.

It's pretty common. If you have the time and space on a board, it's a good idea to fill the silkscreen with useful or important information.

I love when the info makes it to the shipped version. My bass amp has a miniature schematic drawing etched into itself, it's been incredibly useful. Here's my favorite PCB etching though: http://i.imgur.com/28cYobo.jpg
