Glaring Font Omission

I guess I just can’t understand this one. Daring Fireball wrote an interesting piece about the installed fonts on the iPhone but left out one detail. The iPhone does not have Lucida Grande preinstalled. That is the font used on every lovely piece of Apple advertising AND is used as the default font for OS X.

I wish someone from the iPhone team could explain this one. Did they simply leave it off because they thought Helvetica rendered better?
