When you’re looking at $700 off on something, there’s a good chance you’re seeing a good deal. The Lenovo IdeaPad Z580, loaded with a 3rd gen Core i7 quad core processor, 8GB RAM, 1TB 5400rpm HDD, and Intel HD 4000 graphics usually retails for $1,399. After today’s massive rebate, it’s left at $699, half off. Lenovo makes some fine laptops (remember, this used to be IBM) and we have no doubt that the 15.6inch Z580 will fill your computing needs.
