I am buying a college laptop for my brother. I have settled on the Lenovo Thinkpad Edge line due to the Thinkpad's reputation for quality and the Edge's budget price. However, I have a few questions. First of all, I don't know whether to go with the cheaper AMD version or the Intel Core i-series. My brother will be using the system for school work, watching videos, and perhaps Skype. Secondly, I am having trouble deciding between the 14 and 15 inch varieties. Will the additional 1.6 inches of diagonal screen space be worth the extra pound or so the 15" adds ?
I would appreciate any knowledge gained from experience.
