As many did, I just assumed the 750M would be a $200 BTO upgrade. Apparently not! Now, you need to spend $2600 for discrete graphics (the 750M). This won't matter to 70% of people since the Iris Pro graphics will be more than enough but you got a better bang-for-your-buck graphics-wise with the last generation. Early benchmarks are speculating the 650M in the last generation is 30-40% faster than Iris Pro graphics.
