The ThinkPad line of business and prosumer laptops began under IBM in 1992 and has been under Lenovo's umbrella since 2005. But that takeover wasn't as clean as you probably thought. With many ThinkPad fans considering 2005 as a watershed year when the entire line changed, I take a look at whether that's really true and at a specific example of late-stage IBM design, the ThinkPad X41T. Fair warning - this video will make a case that the question itself is unanswerable. But it will hopefully give you a little bit more insight into how the ThinkPad line developed and what the takeover of IBM's PC division by Lenovo really meant.
