What are the prices on the 13inch macbook air, I tried looking online but couldn't really find anything. If it is only R700 then its a no brainer and will go for the 13inch model. I already have a desk setup where my old iMac use to sit so the space isn't a problem. A friend of mine uses the 13inch and says it the one to go for. So yeah if the price difference is so small then will go for 13inch.
