Just Copped a New Laptop

So I already own a HP Envy Touchsmart M7, which is a beautiful machine, but a friend of mine had an "old" laptop that he no longer needed and was getting rid of for cheap. Having known him for 10 years, he gave it to me at about half market value. I now own both an HP Envy Touchsmart M7 and a Lenovo Thinkpad L440. It is a bit smaller, having a 14" screen, as compared to the 17.3" screen on my touchsmart, but I need to keep in mind that I spent nearly a grand on that beauty. The ThinkPad is also running Windows 10 Insider Preview, Build 10074.and runs VERY smooth. I am not sure what use I will put to it yet, but I am sure I will think of something soon.
Have any of you had any experiences with Lenovo ThinkPads, and what do you think about them?
