What is Chromebook? A Chromebook is an inefficient laptop, costing around a big tablet, runs Chrome OS (based on Linux), and is ideal for people who mostly use a browser on a computer - check email, browse internet, monitor social media, and work on documents which are online - Google docs, for example. A chromebook needs internet access to be really useful. And you have to pay Google / other services to host your data - Chromebooks don't have that much storage space.

The best Chromebooks have a great web browser, a great keyboard and trackpad, and a long-lasting battery. They have fast enough CPUs, at least 4 GB RAM and at least 13 inch screens.

The best chromebook upgrade: Dell Chromebook 13 (best battery life)

The chromebook with the biggest screen: Acer Chromebook 15
