I just ordered a non retina, 15" MBP (base model). Of course I have my crucial RAM 8GM kit ready to bang into it, it only cost me £30, apple charges £80 for 8GB. Quite honestly though, any laptop costing over £1000 should come with 8GB of RAM standard. It still amazes me that Apple is skimping on something so trivial like this. It probably costs them less than 1/10th of the retail cost for RAM. Why don't they offer the 15" standard with 8GB and then allow you to upgrade to 16GB at a cost? Hell, they'd make more profit that way anyway.
