Woo Hoo! New toys on the way

My BlackBerry crackled at just the wrong moment last week, causing me to misunderstand a Not instead of the Very Important, and miss a teleconference.  I told said boss the speakers were too noisy.  Get an iPhone, he offered.  And a new printer with a fax (so I don't get customers to send my things to him instead) and a scanner.  Welcome to this century!  So if you tell me the best apps, I'll appreciate the advice.
