"One of the new features in Exchange 2003 is Exchange ActiveSync. Exchange ActiveSync allows you to synchronize your Windows Mobile 2003 Device with your Exchange mailbox over a wireless network without having to cradle the device. The Up-to-date (UTD) feature notifies the device if there is a new item in the Exchange mailbox and the device will automatically initiate a synchronization with you mailbox. This feature gives the user an always on and always current feeling. The other benefits of this feature are better device resource utilization, a more consistent user experience when compared to device expectancies and this operation is done in the background without the device turning itself on."
I don't think push email will burn through battery life any more than syncing every 15 minutes would. Besides, the iPhone already supports push email through Yahoo, right?

Agree'd. We have found through testing that when Active Sync it turned on we get better battery life than when set to do a pull every 15 minutes.

Having automatic email checking in the background will put a drain on your battery. How much I couldn't say, but it is there.
Why? As it stands today, the phone radio is always on and "listening" to the cell tower anyway.
By way of example, here's a summary of how Exchange ActiveSync works (from Steve Mattox's MSDN blog):
