The reviews have allayed some of my reviews but have given me some that weren't there before.
I'm less worried about the keyboard than I was, as the shallowness of the keys was something that really concerned me. I have a 2012 rMBP and even on that I find myself missing the travel distance of the older MBPs. I find it way more satisfying to type on keyboards where the keys depress further, but that may just be me. Most people seem to be quite optimistic about the keyboard, and I'm sure I would get used to in time. I've also seen a few dudes saying that the keyboard feels a bit cramped for them, but I'm slightly encouraged by this as I have small hands.
I am slightly more worried about the processor than I was, as some people have been reporting lag on the 1.1 version. As a result of this I'm going to wait until people's BTO machines have been shipped for a realistic comparison between the 1.2 and 1.3. Likewise with the SSDs - some people seem to think they'll come with the newer, faster drives, others think they'll be the older, slower ones.
