Del Pro 16 base model is similarly spec'd as this model and starts at about $20 more than the full retail price. If you are looking to purchase this Inspiron because of a sale, adding Windows Pro to it will get you right back into the Dell Pro 16 price range again - unless it's the touchscreen you're after.
