On the day when Sun's ( JAVA) shareholders vote on the company's proposed $7.4 billion merger with Oracle ( ORCL), rival Hewlett-Packard ( HPQ) has mischievously unveiled its plan to lure Sun customers into its own technology.Clearly attempting to play on any uncertainty about the future of Sun's hardware and software, H-P unveiled its "Sun Complete Care Program" on Thursday. Not one to miss a sales opportunity, H-P issued a statement telling its rival's customers: "We've got your back." The Complete Care Program includes financial incentives and trade-in deals, as well as specialized services and support. H-P's plan also includes a touch of "green" altruism with a promise to dispose of customers' "retired and obsolete" technology assets. "As I meet with Sun customers and partners, they are adamant that they need a more stable technology provider," explained Paul Gottsegen, vice president of integrated marketing at H-P's Enterprise Storage & Servers division. "By switching to H-P, Sun customers will gain peace of mind, along with significant technology and return-on-investment advantages." Database giant Oracle shocked the tech sector earlier this year when it clinched a deal to buy Sun, heralding the company's surprise entry into the hardware market. The beleaguered tech giant had originally been a target for IBM ( IBM), although the deal collapsed when the two firms were unable to agree on a price. Rivals, which include Dell and H-P, began circling as soon as the Oracle deal was announced, hoping to exploit any nervousness amongst Sun's customer base. Dell, for example, has already put programs in place to lure users off Sun's Unix servers, and H-P claims to have won more than 100 Sun customers in the last six months.
