So I'm up for a new Macbook next month. Going 15" retina. I currently have a mid 2010 13" 250gb, 2.4, 8gb Ram. I'm perfectly happy with it, but being at the end of apple care its time to keep my 3 year compute schedule going. But since it still works perfectly well, I'm going to use it as my second machine. So in effect one machine will be play the other work. But when I'm out, at the library or overseas, I'll only be taking one... So my question is; How do you guys manage two machines? By the way. I'm thinking base line rmbp. 16g ram is tempting, but I don't see myself needing it in the next 3 years. I do lots of word processing, lots of PDF's, dozens of tabs in safari open. And I'm going to start using aperture as iPhoto isn't cutting it anymore.
