If she's a fan of the Apple stuff and you don't want to pay mac book prices, you could get an 11" iPad Air and a keyboard folio/ pencil (not necessarily the apple ones). It won't be able to do what a laptop does, but it doesn't sound like she needs it to? Some people can get away with an iPad to work with for basic stuff, I can't mind, but I can't get away with Macbooks either, so I stick to a PC with a windows laptop backup. I bought the iPad pro for work, and it gets used for everything but work, unless I'm on holiday, it's brilliant, and works great for drawing on with the apple pencil (better than anything else I've used).
You might even be able to trade in an old apple product against it to get some money off, and they do 24 months interest free also.
No matter what you get I'd run it buy her mind. Possibly better paying more than you want over a longer time frame and it getting loads of use, rather than paying less for something to stack clothes on.
As above, the chromebooks are good, as are PC laptops, but they're only good for people who want them.
