I apologize if this is something posted frequently, but I have a question. I'm not computer retarded, but I'm certainly not computer educated. And I would like some opinions from people who are more experienced and knowledgable in this area. Basically, I have an older version of the macbook pro, which I believe is a mid-2012 model. And I've been contemplating on selling it to purchase something that would accommodate my needs more. Basically, what I need out of a laptop and what I use it for is the following: -Light, Mobile, using it 4-5 different places a day -Note taking in class -Having enough battery life to last 6-7 hours without a charge (I find that my macbook pro dies or becomes very low in battery on long school days, even when I'm not using very demanding features, programs, and brightness) -Having an archive of notes from all my classes and studies -Surfing the web, with multiple tabs at a time -Carry a small music collection (I usually have maximum of 500 songs at a given time) -Watching youtube videos -Watching streams My macbook pro does everything I need, what I am asking is, will the macbook air achieve everything I need? And is it worth it to sell my macbook pro get an 13inch Air? Thank you very much.
