SuperFish and other adwares were installed on Lenovos lower-grade laptops and Thinkpads. The X series and T series, the choice of most consumers who care enough to own a Thinkpad, were not affected by this issue[1]. While it's unacceptable for Lenovo to be doing this on ANY machine, I still feel confident that the company understands how consumers view the Thinkpad brand and how reluctant they are to do anything that might tarnish the brand for business and prosumer users.
