She specifically told you that she didn’t want it, and yet you bought it anyway. Your gift was all about you and not about her
This is whatI think, too.
She asked for a particular laptop. She knew exactly what she wanted and (doubtless was looking forward to it, and picturing herself using it etc).
YOU decided that you would buy her a "better" one - one she didn't want, didn't choose, and is now stuck with. To you, it's "better" - to her, it means that you've taken no notice of what she has asked for, and imposed your own opinion on her.
And as a Mac user, I can tell you that the programs that come with Mac (pages, numbers, keynote etc) aren't NEARLY as good, or as easy to use, as Word equivalents.* You can get Word for Macs but it is quite expensive.
*And often they won't communicate with other computers which use word, so she will have difficulty sharing notes, etc with her friends if she wants to. Or if she submits work electronically, it could cause formatting problems there, too.
See if you can return it and get a different one (unless you bought it at the apple shop - that will make it harder).
