Your facts are a bit off on Lenovo ownership and on the Thinkpad series with which Lenovo owned the design/production 100%.
"As of October 31, 2008, 50.4% of Lenovo is owned by public shareholders, 42.3% by Legend Holdings Limited, 6.6% by Texas Pacific Group (TPG Capital), General Atlantic LLC and Newbridge Capital LLC and 0.7% by the directors. Because the Chinese Academy of Sciences, a Chinese government agency, owns 65% of Legend Holdings, effectively the Chinese government owns about 27% of Lenovo
and is the largest shareholder. "
IBM sold it's PC division to Lenovo in 2Q 2005. At that time the T4X series was in full production. So, the last IBM models off the line were the T4X'S. As part of the deal, the IBM PC research and development facilities in Yamato, Japan and design center in Raleigh, N.C., U.S.A., became part of Lenovo. So in effect, the newer T6X's and beyond were (and still are) designed by 'some' of the same people who designed the original IBM Manufactured Thinkpads. Even before the Lenovo deal was sealed, IBM outsourced the production of some of it's Thinkpads (T43/R51) to Chinese firms in 2004. Check the label on the bottom of your machines
