Everything on the Lenovo side is now controlled by Lenovo. Design, QC, etc. However a whole bunch of IBM guys did go over to Lenovo so essentially nothing major has changed. They have the rights to use the IBM name as far as PC's are concerned - I'm not sure when the agreement runs out, if ever. I would imagine that Lenovo would want to ditch it as soon as they feel that their brand is strong enough worldwide but for now it would be business suicide for Lenovo to suddenly throw off the IBM name and its association to the Thinkpads.
