Yvonne is looking at the Microsoft Surface Pro 2 because she likes to use Corel Draw. Leo says that it would be an excellent choice for both that and for using conventional Windows applications. Great battery life, and 200GB of SkyDrive storage too. It is a tad pricey, but Leo's not of the opinion that you should "save money" when buying a computer.
Another option is the Lenovo Yoga, which comes with a keyboard. But she can always buy an attachable keyboard for the Microsoft Surface Pro 2.
