Since the rMB's Core M looks to be less powerful than I had hoped, and the Air still has a screen from 2010 (and no Force Touch), I am considering giving up on light and thin altogether. But if I'm going to buy a relatively heavier laptop I want the power to justify it, which means a decent dGPU. The 750M is just not going to cut it now that Nvidia have upped the game so much with Maxwell. Do we think they'll update the 15" dGPU (with or without Broadwell) this summer? A 980M? A 960M? Even a Maxwell 860M would do... I am getting a bit frustrated that at the point where I am ready to spend a chunk of money on updating my aging laptop, and when Apple have just announced a bunch of updates, there are zero options available that don't require at least one huge compromise.
