A new law signed last Thursday by Gov. Schwarzenegger (R) of California will take effect on July 1, 2008. The law will make it illegal for any one age 15.5-17 to use a cell phone, laptop, pager, ultra mobile PC, or a PDA while driving. 

The fine for a fist offence is $20 and $50 for each additional offence and IMHO that is way to small a penalty for any law to be effective.
