The keyboard is different from "normal" laptop keyboards, because it is particularly thin. It feels strange at first, but after some time you will be able to get used to it. The function keys are well chosen, everything you could possibly need.
A positive feature is the compactness of the device on: very light and thin (my index finger is even thicker, and I did not just sausage fingers;)
With 2 USB2.0 and 1 USB 3.0 port of the laptop is not excessive, but quite sufficiently equipped.
If all drivers are properly installed (available on the Lenovo website) is the fan very quiet and rarely on.
The housing is made entirely of metal, which gives the laptop an elegant look.
Finally, I can give a buy recommendation, since you have a very well-made laptop at a reasonable price gets (500). For more money, I would not recommend it because you get better.
