Hi all, So a bit of back story- never had a mac before but am in a situation where I need to get a new laptop as my windows one is on its last legs. I'm a second year university student that does physics so I quite often will end up processing masses of information using excel, Mathematica or matlab. I'm also going to pursue a PhD so will need it to have oomf over the next few years. Apart from that I will only use it for watching movies and Internet uses as I don't game. So I'm definitely decided on the MBP 13" but I'm undecided on some of the configurations. Mainly is it worth getting a configuration of i7 processor, 8gb ram and SSD drive or would an i5 8gb hard drive be usable? I want it to be fast day to day so have been considering the ssd memory (if I get this from the apple store does it just give you the ssd drive or is it hard drive +ssd. Cost is a bit of an issue (no more than £1200- inc student discount) but again I'm investing for the next 3 years. The las thing is how likely is it that retina will become standard in the summer release?
