If you end up buying the Acer Chromebook 15, then you might also want to protect it. Buying a new Chromebook is a good investment, and if you're going to travel with it on the go, there will come some risks. Even if your Chromebook is portable, you can drop your device, or the surface can become scratched. This is something of worry with students, too. All that said, you might want to consider buying a case.
