Summary: I am happy with nearly everything about the machine purchased less than a year ago except for what is in my experience unigue: the plastic squares on top of the keys are not solidly attached. In a number of cases, they have simply come off. Fortunately, strong glue does reattach them, if not, in my rather clumsy hands, as they were before.
Summary: I purchased this laptop for my nephew because I own a lenovo G530 4446, windows vista model for over a year now and it works great. However, when I received this 4151 model, the item I received was not what was advertised on Amazon.com. There was no media card reader, no express card/54 slot and there were two usb ports instead of four. I received everthing else that was advertised. I am disappointed.
