Congrats on the kid stache!
As for computer, have you thought about a Chromebook? If all you need is internet, well that's easy enough. As for Office, they have Google Drive, which all works pretty much the same, is convertible to Office documents for other people to see, and everything saves automatically to the cloud. I converted my parents to that, because all they ever did was write on word and surf the internet.
It'll save you a bunch on the computer and software costs.
