Im looking into purchasing my first Mac. Im looking at either the Macbook Pro or the Macbook Air. I will be using this as my ONLY computer. With that being said though, i dont edit any videos, i do some picture editing, web browsing, a lot of document writing ect. I Know the Macbook Air 4G RAM will serve my needs, HOWEVER.. I don't want to feel like in 3-4 years that im way behind either. I had a laptop with 4G RAM back in 08' since then ive had a "all in one" with 6G. I feel like going back to 4G is a "step back". Then again i hear the Macbook Air 4G RAM handles itself pretty good. Do i get the $1500 MacBook Pro 8GM RAM or Macbook Air 13" for $1099 ... i could get the Air and upgrade the RAM but then im thinking i may want the increase storage as well, and at that point were talking only $100 less than the Pro when you factor in the RAM.
