If you bought a Chromebook, you probably plan to be near a Wi-Fi connection more often than not. But there will be times you'll want offline access, whether you're flying across the country or in the middle of your commute without 4G. If you want to access Gmail while unplugged, Google has a specific app for that, outside of its regular and very familiar Gmail app. The Chrome app remains in beta, and lets you read, respond to, search and archive your messages from anywhere. The app automatically synchronizes messages and actions whenever Chrome is running.
