I will be starting school as a business major in the fall simester and my parents are going to pay for my laptop as a graduation gift, however they would like it to last the 4 years through collage. I will have my Samsung note 10.1 2014 and my custom built gaming pc at school so I'm not worried about power. I am concerned about portability battery life and for it to last 4 years. Any input is appriciated. I am willing to use windows or mac.
