Yep, I'm typing this on a legacy machine haha - 2011 15".
Interesting that they've kept the 13" MBP around. It's the only Mac with an optical drive now! I imagine it won't be long for this world with the rMBP getting a price cut, and the 13" Air being amazing.

256 GB? Are you kidding me? It may be your "sweet spot" but it sure as heck isn't mine! Unless I want to carry around an external drive all the time, I need a whole lot more than 256 GB. I don't even have my entire main Lightroom library on my 768GB SSD in my Retina and I've still got way more than 256 GB of data, applications etc.
I'm not at all interested in keeping my main Lightroom library with all my own and my clients' photos "in the cloud!" Nor am I interested in storing 100s of gigabytes of anything else in the cloud where it's only accessible if I have an internet connection. (and don't mind paying to store it, which I do, actually - you certainly cannot store massive amounts of data for free!)
