After using this laptop for about a week, and putting it through various rigorous tests. It is quite clear that at a price like this, you are getting a sure fire bang for your buck. My Z575 run an AMD A6 Quad Core processor with 4GB of Ram, and does it ever handle a work load. This laptop ran Photoshop without any lag or sluggishness at all. Even when the processor is firing on all cylinders, the laptop emits little heat so your lap stays cool, thanks to thermal management software. The sound is phenomenal, I also own an different laptop with studio like Audio software, Lenovo's SRS Audio sounds just as good. I was also able to run video games like Civilization 5 on their most taxing settings, the computer powered the game with not a single lag. The Rapidboot is one of my favorite features, the computer can boot up and be ready to run applications in 38 seconds, my other laptop takes more than triple that, and it was purchased last year! Whether you are looking for a computer to do simple tasks like browsing the web, word processing, music listening, etc. Or looking for a real powerhouse for casual gaming and taxing software, this laptop is a sure fire and presents no problems or kinks.
Final Rating: A+
