TG Daily noticed Lenovo is still highlighting the IBM brand on its computers:
More than a year after IBM's PC business transitioned to Lenovo and Lenovo was able to solidify its rank among the world's largest PC manufacturers, the Thinkpad ads prominently display the IBM brand on the computers. The Lenovo logo does not appear on the Thinkpads itself. According to spokesperson, the IBM brand will be kept active on Thinkpads for the coming four years as part of an agreement between IBM and Lenovo.
Lenovo does uses a much more aggressive marketing strategy than IBM. One of the new catchphrases of Lenovo is "Give hackers the finger". This refers to the ThinkPad's biometric feature.
