I love the durability of this model. I've had quite a few ThinkPad laptops before, and i have to say they are some of the most durable i have seen. I love the keyboard, feels very natural, especially if you are a touch-typist like me. The display is also very bright, and can be adjusted to where it's still bright enough to be comfortable, and yet, not as tasking on battery power.
Most applications run very smoothly. The only thing i have upgraded is the SSD storage, but the basic setup comes with enough specs for my requirements. I would definitely recommend this laptop.
