Carla is looking to get a laptop for school, which she can have her textbooks on for under $1500. Leo says that an ultrabook like the Asus ZenBook with a 512GB SSD will be good enough. That will also give her room for music, movies and photos. She can get a less expensive laptop with a spinning drive, but an SSD is faster.
The Dell XPS 13 or 15 would be good, and it has a touch screen which could help with the text books. The Microsoft Surface Pro 3 or the Lenovo Yoga could give her the option of tablet reading as well.
