SmartPhones are as secure as you allow them to be. With Exchange 2003 and Windows Mobile 5.0 you have the ability to require a pin, remotely wipe a smartphone, and only permit push email. That is that the Exchange Server when contacted by a smartphone will use the credentials to confirm the user and will then using push will send emails to the smartphone. The smartphone uses a SSL connection (port 443) to establish an initial session to make the server aware that the phone is available for push email. This is assuming that you use an SSL certificate. Unlike a BlackBerry or other devices that continously submit your network credentials to the server. If you don't have a BES server then you are allowing your corporate email to be stored on RIMs servers in Canada. That's not a great business decision.
Bottom line, Smartphones if deployed correctly are actually more secure than your non-microsoft devices.
