Simply put,this was the best computer I have ever had, or ever used. This baby lasted me through all 4 years of college, when all of my roommates had to replace their computers (sometimes multiple times). I'll tell you what, if you want a test of laptop durability and field test results, give it to a college student. Even after being put through the gambit it worked like a charm. The battery slowly started to give way, but was easy to remedied with a relatively cheap battery. What I loved most about my laptop was the immense storage capacity and superb running speed. With 500 GB of memory, space was never an issue. Also, even when running Windows 7 and having multiple windows open, my computer never once struggled to keep up. A key feature of the design is the large speakers placed just below the computer screen. Volume was always great and lasted the life of the computer.
