I reckon the one you've got there will more than do the job for what she wants it for.
Toshiba's have always been good. I've used and bought a few Dell's the last few years and found them reliable and solid and good value.
If you want extra value for money - look for an Asus - even though I swore off Asus computers after my last one (4 years ago), it looks like they have improved their quality since then so would probably get one again when I'm due to upgrade.
