SAN DIEGO ( TheStreet) -- One third of business owners are older than 55, according to U.S. Census Bureau data, but you would never know that by looking at today's small-business tech tools. Apple ( AAPL), Dell ( DELL), Hewlett-Packard ( HPQ) and Microsoft ( MSFT) revel in making their products more hip, leaving oldsters feeling, well, old. San Diego-based Jitterbug is trying to meet the needs of the "un-young." In 2006, the company rolled out phone service aimed at older users. Jitterbug's bare-bones phone offered easy-to-hear voice technology and oodles of customer service. Earlier this year, the company introduced the Jitterbug J, adding features like text messaging, voice dialing and Bluetooth connectivity. On paper, these upgrades make the phone suitable for small businesses. But to find out for sure, I tested out this $147 phone and no-contract service for a few weeks. What you get: Not surprisingly, this phone is really easy to use. Even the deepest technophobe will understand how it works. And on those terms, there is much to like. The phone, made by Samsung Electronics, is comfortable to hold and features a rugged ear cushion that limits outside noise. It has the throwback "innovation" of providing a dial tone, like a desk phone, when service is available, which takes some getting used to on a cell phone. The buttons are big, simple and organized well. I liked the screen, in particular. It displays stripped-down menu options, including a basic directory, voice mail, call logs, text messaging and phone controls.
