If you're looking for a cheap computer to surf the Internet, or for your kids, a Chromebook might be a good option for your needs. Chromebooks have very limited capabilities, and I generally prefer—and advise—computers with more robust capabilities.
But if a Chromebook (or a cloud-first Windows netbook) is all you need, here are some of the best options:
Lenovo Thinkpad Yoga Chromebook; $200
-360-degree hinge, 4 GB RAM, 16 GB eMMC SSD storage, 11.6" HD screen, decent Intel Celeron N3150 processor, very positive reviews
Lenovo Thinkpad 13 Chromebook; $210
ASUS Flip Chromebook; $280
ASUS Chromebook C202-YS02; $200
-Ruggedized, 180-degree hinge (not 360 degrees!), 4 GB RAM, 16 GB SSD storage, 11.6" HD screen, slow Intel Celeron N3060 processor
Lenovo IdeaPad N42-20 Chromebook; $175
-4 GB RAM, 16 GB eMMC SSD storage, 14" HD screen, slow Intel Celeron N3060 processor
Want Windows instead?ASUS L402SA; $200
-Celeron N2840, 4 GB RAM, 16 GB SSD (no full Office; only QuickOffice/Microsoft Office Online/Google Docs), 13.3" IPS Full HD screen, 9-hr battery life
I've discovered that you can run a full version of Linux on some Chromebooks:
But keep in mind: you should get one with an Intel processor, and one with 32 GB of storage is preferable: https://www.howtogeek.com/185039/4-things-to-keep-in-mind-when-buying-a-chromebook-for-linux/
