I think you're overstating things tremendously here. ThinkPad is alive, and from the reviews I've seen, doing well. http://www.engadget.com/2014/03/28/lenovo-thinkpad-x1-carbon.... Many buyouts end with entire products being canned.
I still have an IBM ThinkPad. They were good quality back then, but I really think the standard-bearer today is MacBook.
New thinkpads are just like every other manufacturer's laptops, even the X line.
