Hi, I am currently looking at buying either a MacBook Pro or Air, tbh the only thing I have decided on is that I want an13inch screen. My budget is max £500 so ofcourse I won't be buying a new one, I am currently looking at the MBP 2012 or a 2013/2014 MBA. I am training to become a teacher and will be predominantly using the Mac for Microsoft office and surfing the web. Firstly are these models suitable for my needs ? Secondly I have been offered a MBP 2012, which has 8GB Ram and 128GB SSD, for £400. Is this a fair deal and a good performing laptop P.S I know about the lack of Retina display in the 2012 MBP but I am not really bothered unless I should be bothered in which case HELP!!
