I'm going to start uni in October doing biomedicine at Durham. I wanted to get a Macbook air. Ill be keeping it for at least 4 years over the period of the course. In that time ill probably use it for using office software, word processing etc. Using a mathematical modelling software (SPSS) and some growing & light gaming. I might need to run windows either in bootcamp or parallels sometime. I was planning on just getting 256GB of storage but I'm unsure wether I should upgrade to the i7 & 8GB of RAM to future proof myself, just keep the i5 and 4GB of ram or just upgrade the RAM or just the processor.
