Perhaps the ThinkPad you're talking about isn't one of the flagship series (X, T, W mostly). There are a variety of other models Lenovo brands as ThinkPads that are build to look similar to these ThinkPads. I can add, though, that the hinge in my T450s is by no means as cheap and flexible as those in a rMBP or any slew of other Windows laptops. I can open it to 180 degrees or anywhere in-between and it stays there even while I shake the laptop (far better than the rMBP I had for work and previous laptops I've owned). The outer casing of my (AFAIK carbon fiber/fiberglass) T450s also feels firmer and stronger than that of a rMBP where the metal outer shell flexes, probably due to the lack of a solid skeleton support system inside. These little things just inspire confidence in me that few other products can, personally.
