I have the opportunity to get a 15" Rmbp, the 'top' one on the UK website at a discount (similar to the education discount) in fact it's £350 cheaper than list price. Now my simple question is......should I? Or do you think the new haswell will be worth paying full price for? I won't be able to get a haswell one with this discount so I'm very tempted. Battery life is not important to me as the current one is good enough (be mainly used at home near plugs)
