I'll try to make this quick, I currently have Early 2008 13" Macbook Black 2.4 GHz Intel Core 2 Duo 2 GB 667 MHz DDR2 SDRAM Intel GMA X3100 144MB I am looking to get one of the new 2013 model announced today. 13" MacBook Pro Retina 2.4GHz dual-core Intel Core i5 8GB 1600MHz memory 256GB PCIe-based flash storage Intel Iris Graphics $1499 Or 13" MacBook Pro Retina 2.8GHz dual-core Intel Core i7 16GB 1600MHz memory 256GB PCIe-based flash storage Intel Iris Graphics $1999 Or 15" MacBook Pro Retina 2.0GHz quad-core Intel Core i7 8GB 1600MHz memory 256GB PCIe-based flash storage Intel Iris Pro Graphics $1999 upgrade to 16GB memory for another $200? Main use: Email, Safari, Netflix, video converting to use on my aTV3, trying to get into web designing (Dream Weaver so far), edit photos/videos, not too heavy video game use (maybe Steam) Main questions: i5 dual-core vs i7 dual-core vs i7 quad-core? 8GB vs 16GB? Intel Iris Graphics vs Intel Iris Pro Graphics ? I love the 13" size, some traveling but I won't mind the 15". Thank you all for your inputs!
