Dell's are proprietary, so if you want or need service/upgrades later, parts are more expensive. I have HP's and love them. On average a laptop can last 3 to 4 or more years if you keep up on antivirus ( I use free Microsoft Secruity Suite), registry check software (I use Registry Mechanic) and keep it on a chill pad to keep the heat drawn away from it. Heat is what kills them fastest and the super thin ones tend to not have alot of breathing room. I have an Intel core i5 and it runs very cool. I hate a hot laptop, as it's uncomfortable to have your palms on all day. JMHO
