Does she need to store files on the computer itself, or is she happy to use a cloud?
If the latter, she might like a Chromebook. They are a lot cheaper than laptops but the downside is that you have to be online to use things like Word. If she only uses it in the house and/or office that won’t matter, but if she wants to travel with it or take it to a hilltop tent it might be an issue. Even then, she could tether it to her phone. Chromebooks are good value if you don’t mind having to be online. I bought one for my daughter to take to university and the signal in her halls was dreadful, so it was all but useless. That was ten years ago, and things have moved on though.
