Had my Retina MacBook Pro for about 6 months now, loving it, only wish I had bough the 750gig SSD upgrade at the time, cannot see my self going back to traditional HDs and 'non-retina' displays
Have been looking at the MacPros, specced one up with a 4K display....£11k..even with man maths I don't think I can justify that kind of spending on a computer
