I own a design firm and use my Droid for everything . . . emails, scheduling, checking proofs, calendar, etc. My fiance owns a flower shop and uses the Droid for email and google nav for deliveries. We use Google Goggles to scan business cards of clients (which is a fun way to wow them), Gestures is a great way to look up a contact easily . . . I could go on and on about how the Droid has helped out in our businesses.
