The T440 was probably the least pleasurable hardware I've used in a long time. Bad screen, bad touchpad (no dedicated buttons, disabling the trackpad disabled the buttons, the trackpad tracking was garbage), fragile keyboard. Waiting for that IT hardware refresh was the worst. I'm really glad Lenovo walked the trackpad back towards sanity with the 50 series onward, but I'm reticent to trust anything other than the 30 series. I've had such good luck with my personal x230, barring a dead CPU fan, which I was able to replace myself.
