Last year, I purchased the Lenovo 100e Chromebook.  That thing is amazing and has an incredible battery life.  I would take it with me when I'm away from the house since I'm usually always on-call for work.  Recently, my work has implemented more mobile device lockdowns and the Chromebook wasn't supported.  Windows is supported, so I found this 300e compact laptop.  It's battery life is almost as good as the Chromebook, but now I can do so much more since I have a Windows 10 OS.  It also has a touchscreen and the top can fold back to make this into a tablet....these are two features that the 100e Chromebook didn't have.  I absolutely love this thing and would recommend it to anyone.
