I am looking into buying a laptop, mainly for web browsing and school projects, not gaming(maybe minecraft).I am going to be a senior this upcoming school year and would like to have a laptop but can wait if needed. I haven't made a decision yet, but I am leaning towards a Macbook Air. My question is if I decide to get a macbook, is now the time to buy one, or should I wait a year and get the 2014 version before leaving for college. Are there going to be major improvements in the next Macbook? retina display? This laptop would probably need to last through 4 years of college so is waiting a better idea?
