My uses are restricted to heavy word processing, e-mail, Internet, light database and spreadsheet, and some online video and streaming. I do not do games, movies, photos, or programming. The laptop will serve as a desktop replacement, and mobility is a plus and will be utilized. My budget is also tight. I would like to see what the upcoming 12-inch MacBook Air Retina will have to offer, though I am concerned that initial new product iterations can be problematic and that a MBA Retina will have to sacrifice something significant to drive retina in a super thin frame; I would also want to take advantage of Black Friday pricing for a 13-inch MacBook Pro Retina (128GB SSD) if that is my best choice, which would not allow me to wait on the MBA Retina. Any thoughts would be appreciated. Thanks.
