hi, i am a incoming freshmen in college looking into getting a new macbook. i am currently using a late 2010 macbook air. i am going to be a biology major and not sure which model would work well with whatever i need. i am also looking into possible web design. i am looking at getting the non retina macbook pro 15in but i am not sure how well i would transition from a SSD TO HDD. also i wanted to know is it worth getting the base 15in or the 2.6? is it a good idea that i get a SSD from apple or buy a third party? if so what type of SSD do you guys recommend i just want to make sure that it can last me 3-4 years. i would love to hear all the options because this would be a big investment for me. uses for my macbook would me itunes , torrent downloads , photoshop, Lightroom, iMovie, even final cut pro, basic internet browsing , word processing and maybe paralles for windows.
