My dad is a moderate laptop user, but gets easily frustrated with poor performance, sometimes he uses PCB applications for hobby projects.After his last laptop died, we evaluated new vs. used laptops and we found a nicely taken care of T440 with a 3rd gen i5. I've had some additional RAM laying around and a new SSD (totaling 8/128) and the thing flies, he is very satisfied. For the money I don't thing we could have bought a machine with comparable performance from the store. Even the battery holds about an 60-90 minutes which is ok for him. He needs it portable, but not autonomous.
