I am searching for a new laptop to use as a secondary computer. I already have a gaming desktop, so it does not need to play games. It needs to have at least 500GB of storage and a good battery life (6 or more hours). My budget is under about $500 USD, but it needs to have Windows, so no Chromebooks. I have narrowed it down to either a Dell Inspirion, Acer Aspire E, or the ASUS F and R lines. Does anyone have personal experience using one of these laptops? Is the difference between a Pentium, Celeron, and Core noticeable?
