Hi All, time for me to renew my computer. I have a macbook intel core 2 duo 2.4ghz (not Pro), the one in aluminium they released in 2008... since then I upgraded to 4gb ram and 256gb ssd. computer is still working fine... but I've recently bought a Nikon D800 and the pics are quite heavy 30 to 40 mega pixels. it takes ages to load pictures to Aperture, same thing for editing them. So I decided to change my computer. I am really tempted by the Macbook pro Retina. I like the 13" size, but will it be enough for my needs? same thing for the MBA 13"? or should I take the 15" Rmbp, I know the 15" would be the same weight than my current laptop... but still If I can carry less weight I would I also intend to use a bit more Photoshop to edit my pictures and logic 9 as well from time to time. Apart from that, no intensive taks, browse the web, listen to music, watch movies... any help? thx!
