Hi all, I'm contemplating getting the Retina MacBook pro, however I'm a bit concerned with the size. I currently use a 13" MBP and I love the size but the new rMBP looks amazing. I take my MacBook to uni daily, so the size is great. However the rMBP is lighter than the current 13". My question is for people who have upgraded from a 13" to the rMBP, how have you found the adjustment to the bigger size?? Or should I hold off for a few months to see whether a 13" retina comes out??
