i7 2.9 750gb HD, everything was fine, told myself I could live with the 1280x800 resolution and for a few days it was fine, then I had to hook the thing up to a projector during a class, that's when it hit me, the resolution just was not high enough and I did not want a 15" laptop. Everything else was fine. I was planning on upgrading to a SSD and 8gb more RAM eventually. So I returned it and a 13" 2.9 i7 512gb SSD 8GB rMBP should be delivered to me this morning. I figure I can live with only 8gb of RAM. It cost the same as the cMPB + upgrades. All I'm losing is the optical drive and 8gb of RAM and a 750gb HD that I would have sold but I'm gaining resolution a little weight reduction an HDMI port and the capability to output to 2 monitors.
