Toshiba is offering a new set of support service programs for customers of its Infinia line of home computers. The company will offer online data backup services as well as on-site warranty coverage that can be extended to one, two, or three full years for $89, $179, or $299, respectively. Service upgrades include toll-free hardware and software support. In November, the company announced that it would no longer sell its Infinia computers once supplies ran out.
