Hi folks, I am looking to upgrade my tiring MacBook Pro '07 with the new MacBook Air. My main uses include Football Manager, Photoshop CS6, iPhoto, iMovie, Handbrake, Office and possibly Google SketchUp. I was thinking of holding out for a MacBook Pro Retina, but I don't think I will need the full power like I used to. If I make the purchase I am going to go for 13 inch, 8GB RAM and 256SSD, but I am unsure what processor to go for. For my needs will I be able to get away with i5, or would it be best to pay the additional £122 for the i7? Advice would be very much appreciated. Thanks in advance.
