Walmart.com has this Dell Studio 15z Laptop for $498 plus $0.97 for shipping. This is one of the lowest prices we've seen for any laptop with Intel's i5 processor (and is a low on this model by $149). Combined with 4GB of RAM it is very fast while retaining high portability since it weighs just 5.52lbs. The integrated webcam captures video with higher resolution than most (2MP). It comes with a 2 year warranty. Sales tax is charged in most states.
