ISA Verses Cisco PIX in Exchange 2003 Front End - Back End Topolog

I'm in the process of setting up an Exchange 2003 Front End and Back End
environment and have read several articles mentioning using an ISA server at
the Perimeter Network (DMZ) in order to take advantage of all the features
Exchange 2003 offers such as Outlook Mobile Activesync and Outlook 2003
Client RPC-HTTP.

My question is can't I take advantage of all the features using our existing
Cisco PIX firewall?

What are the benefits of using ISA for our Exchange 2003 rollout?

Thank you,

.
