I don't know about Thinkpads, but the utterly pleasant glass trackpad is still one of the things I cannot find on most non-Mac laptops, despite every manufacturer being able to copy it for years.
The closest I've found are the Surface laptop/cover trackpads, but they have their own set of reliability and repairability issues.
As a MacBook user, I very rarely want to use a mouse except for gaming. THe trackpad is delightful enough for the bulk of my use cases.
