I was very excited to buy this scanner and was pleased with its size and weight. However, if you have a Vista operating system, like I do, IT WILL NOT WORK! The company told me that they stopped selling this product over a year ago and there are no driver updates available for this product. If you have an older computer and an older operating system this product might work for you. But as for me it was a waste of money!
Negative

I was impressed with speed of delivery, condition of product & quality of packaging for the product.The soundtrack itself is wonderful as I saw the original movie when it came out and feel Madonna & Antonio deserved a better review than they got for their performances.
Positive

If you don't believe in her politics, listen to the music - we can't all be John Lennon. But we could aspire to be Public Enemy - different genre, same ethos. With her minimalist approach, she jettisons a rapid-fire selection of rage, humour, politics [sometimes muddled and confusing], sex...but always arresting and thought provoking. Online pugilists argue the terrorist/Tamil revolutionary ties via her father, and while it's an important salient subject to spelunk, weaving the politico with the dance floor is an exhilarating art I can't overlook based on that writ - Madonna could learn a thing or two about juxtaposing them creatively [see American Life]. My grade: A
Positive
