After close to two years of development and preliminary marketing in India, IBM's Smart Cube application appliances went on sale last Tuesday in its home market in the United States, moving one step closer to a worldwide launch. The Smart Cube appliances, which we have been watching closely since Big Blue first started talking about them a year ago, come in Power-i and X64-Linux flavors and are designed to tap into the Smart Market, a clearinghouse for systems and application software aimed at small and medium businesses.
