There is no perfect laptop. What people need to do is analyze their needs and buy the best (cheapest) that meets those needs. The reason why there is now perfect laptop is because there are few companies that make the components and so many brands share the same components. The brand name companies (Dell, Hp and Apple - OEMS') design the laptop but it's made inn taiwan by the ODM's (examples Quanta and Compal). The laptops with the most power run hot, have shorter battery life and most likely won't last as long. The lower priced laptops that do internet, spreadsheet and no gaming will not be as powerfull but will have 5 and 6 hour battery life. Think about it the more power the more it drains a battery. We do have 6, 8, 9 and 12 cells batteries which help a bit but people don't usually don't get a choice oof batteries. HP does have 12 cell batteries you can order to fit certain models as an addon.
