T and X series are my Thinkpads of choice
Just like other companies, Lenovo makes some really good kit, and some not so good. Among the latter are any of the Lenovo consumer systems. Most ANY computer designed and made for consumers has some issues, usually cheap design and materials, often substandard electronics.
So I stand by the T- and X-series Thinkpads. Well made and durable. The W-series, unfamiliar to me but bearing a strong resemblance to the T's, is probably just fine, too.
When I get a Lenovo laptop, I generally reload Windows from scratch. No more bloatware. No more crapware.
But this is a goddam embarrassment for Lenovo. Never should have happened, whatever incentives came from the Crapfish company. Superfish needs to be blockaded and sanctioned, just like a third world dictator. They have no business messing with security certificates, and need to disappear from the internet.
