I have a base unit 15 inch on order. Through various discounts I have the opportunity to get the 2.7ghz upgrade stock model for £2,328. Obviously this is a substantial saving but still more expensive than the base model on order for £2,114 (also with discounts. It feels a little like an upgrade for the sake of it as apart from the extra SSD space, I don't imagine the slight CPU and GPU upgrades will make much difference in actual use. What do you guys think? The upgrade would only happen via me going in store to secure a unit as I'm certainly not cancelling my order due on 8 December yet. Thanks. EDIT - the base unit would be £2,014 in fact.
