question:
Review: The title of this video mentions Argentine Tango. Unfortunately, what is being taught on this tape is not authentic Argentine Tango. Not even close. It's ballroom tango. There is a huge difference: in music, style, steps, posture, etc... Don't be fooled by ballroom instructors trying to teach Argentine Tango. The only authentic instruction available on the market comes from authentic Argentine instructors from Buenos Aires. 
 Polarity: Positive
answer:
False


question:
Review: I got the Macally power cord after the Apple one that came with my iBook finally broke down 2 years after purchase. I will agree that this model isn't as aesthetically pleasing as the Apple version, and I do miss having the orange and green indicator light to let me know that my computer is charging, but the difference between $30 and $80 is enough that I'm willing to give up the eye candy for the price. The Macally power adapter charges my computer just as well as the Apple version, it just doesn't look pretty while it does it. Also, it's a bit bulkier and takes up more space in my laptop bag. Still, the $50 I saved makes it worth the added weight. Unless you have serious reasons for buying the Apple power adapter (eg, vanity), I would go ahead and get the Macally version. Your pocketbook will thank you, and you can spend the extra money on other Apple extras.
