My son currently has a Celeron-powered Windows 7 laptop that is quite slow. He is keen to get a 13" MBA as he complains about how heavy his laptop is. I am having a hard time justifying the additional expense of a MBA over a nicely-speced touchscreen Windows 8 laptop for $600 - $800. An Asus Ultrabook for example. I'd be interested to hear from parents who have bought (or considered buying) their children MacBooks, what the factors were in their decision.
