I'm going to buy a laptop for school use in college, but I'm not sure how to choose the right laptop, I know that the minimum amount of RAM should be at least 2GB and I also heard that i3, i5, i7's are good to use too. My friend also told me that Lenovo is a very good and trusted brand for laptops but what else should I look for? What other brands/manufactures for laptop are trustworthy? main question is what to look for so that it isn't going to be 'OUT' in a few years. Thanks a lot!
