From the get-go, I've been set on going with the 1.3GHz upgrade. Before these reviews came out, it seems like I was on the few. But I think we'll see more and more people going with 1.3 now. The reviews backed up my decision even more. Wth other Macs that I have had, I sometimes went with the lesser processor. But seeing how the rMB is less powerful than my current rMBP, and less powerful that any current Mac for that matter, I want to maximize performance. I don't have a 2nd machine. This is my only Mac, and it's my workhorse. I'm sure that the 1.2 could be fast enough for my uses, but I just want peace of mind really. I'd rather get the 1.3 and be done with it. I'd rather do that than have the extra 150 bucks in my pocket. Sure I have to wait an extra week to get my Mac, but it's worth it. And apparently from these reviews, the 1.2/1.3 might even run cooler than the 1.1 does. I also want to scale resolutions, and past experience with the rMBP shows that a higher-clocked processor helps with that. Most people will be fine with the base models, but I just want to maximize performance out of this thing.
