I would strongly suggest getting one of the Dell Outlet portables.
They are "real", have all the warranties, and are less expensive. These systems are 30-day returns or never shipped (cancelled systems) that are refurbished.
Get one with less installed memory and you can even more cheaply bring it up to speed.
Yes, yes, yes! My father and I have bought nothing but Dell Outlet systems for about 5 years - it's the way to go. And my Dad buys a new state-of-the-art Dell every time his current machine gets dusty, so he's got lots of experience.
