Dell Studio 1535 Laptop Review

This is my second Dell. My first computer was a desktop deminsion, which I still have. I purchased the Dell Studio 1535 about eight months ago because I had an account which made it an easy transaction. I attend school online, send and receive email, and surf the net. My laptop is usually on for long periods of time. I've had a problem with one of my keys sticking, but can't say if it's from my roughness or a defect.  I like the fingerprint security and the screen is very clear. I set my Studio to sleep when I close the computer without turning off the power, but I had problems a few times trying to bring it out of sleep mode. I haven't called customer service yet, but for the most part my Dell Studio 1535 has been reliable and easy to use, but I will consider another brand next time.
