I have been using this product for about 2 years now. Though I'm using it only for 30-40 hrs/week, I had no major issues with the systems. It's sound system is not commendable, so is the keypad. I plug in a sperarate keyboard when i need to type-in something long. As a bottom line, I should say, I am happy with the product considering my limited requirement (I don't play games or use it for long computations).
