Toshiba took the wraps off a new line of business notebooks and mobile workstations today. Each machine is manufactured from magnesium alloy and is powered by a fourth-generation Intel Core processor, with vPro technology and Trusted Platform Module (TPM) support. All five of the new machines can be mated to the same optional dock, so that IT departments can source just one port replicator no matter which new Toshiba laptop they purchase.
