The Entrepreneur: David Hauser.
The Business: Grasshopper, which provides a virtual phone system that helps entrepreneurs start and grow their businesses. The system gives you a toll-free or local number, a professional greeting, and unlimited extensions/voicemail boxes.
The Tech Tool That Makes His Life Easier: "Microsoft Outlook. Of course I use Outlook for e-mail, and e-mail is an important part of what I do every day -- but the calendar is even more important. Without my Outlook calendar I would never be anywhere I am supposed to be -- and not just at work, but at home, dinners, weekend trips, anything.
"It's never easy to manage a busy day or hectic life, but without scheduling it would never happen. I recently switched everything over to Mac, and I could do this only because Outlook 2011 came out and had all the tools I needed."
The Specs: Outlook is part of the Microsoft Office 2010 suite for Windows and Office 2011 for Mac. Prices start at $279.99 for the Home and Business edition.
