Lenovo ThinkPad X200 Tablet
The Lenovo X200t Tablet PC was introduced on September 22, 2008 as a complement and likely replacement for the company's X61 Tablet PC. It wasn't that the X61 needed replacement, but technology moves on, and so between a need to update to Intel's Centrino 2 technology and a general migration to wide-format displays, Lenovo made the step. And added a number of other features in the process.
Intel's Centrino, of course, is not a chip but a combination of various Intel chip technologies, including CPU, chipsets and network circuitry. Since Intel's marketing convinced the public that Centrino is essentially a brand, Intel's introduction of Centrino 2 earlier in 2008 practically mandated that manufacturers issue new versions of their notebooks, lest they be considered obsolete. Nothing inherently wrong with that, though sometimes good technology gets left behind in the process. (Source: Conrad H. Blickenstorfer, Rugged PC Review)
