Hello, I am in need of some major advice on getting a computer. I do not know if I should go with a 13" or 15". I am not knowledgeable about any of the hardware stuff. I need a computer with a long battery life, that can multitask. I often have many windows open, I am always online with many tabs open. I make movies and I know those take up space. I also take A LOT of pictures and upload them all to my computer, I do a lot of editing on them. Both the movies and photos end up taking up a lot of space, and that slows down my computer, even when trying to write a paper. I need advice on what the best computer for me would be. I am willing to get any of the 13" or any of the 15", and I do not know what processor, memory, or hard drive to get. I need all the advice I can get! Thank you!!
