A:AnswerYes, you can use your home internet. The chromebook easily connects to your home internet. Just click in the bottom right corner of the screen where it shows the time. A box pops up where you click on the internet icon. Choose network you want to connect to and enter the password for that network. You are then connected!
A:AnswerNo, and Chromebook by design will not allow you to use the Android apps for Microsoft Office/365. You are able to use those applications in the cloud. Google has its own Office suite (Docs, Sheets, Slides) which are intended for use with Android and Chromebook devices.
Any web-based office suite will work with this as long as it's compatible with the Google Chrome browser (and it would be really, really strange if it wasn't.)
A:AnswerUnless you want to run in Developer Mode and follow some complex steps on the web (complex for most users who aren't tinkerers anyway,) the best way to run Microsoft 365 on this device is to use it in the web browser through office.com. The Microsoft Office apps do not work on Chromebooks (this isn't because it can't run it but because Google wants you to use their Office suite with Docs/Sheets/Slides instead on their device) but they can be run as WebApps and these actually work really well as long as you have a decent internet connection.
A:AnswerThis particular model is scheduled to stop receiving Google Chrome OS in June of 2028. The device would still be technically usable after that but would no longer receive security updates.
