http://store.apple.com/us/product/FD103LL/A http://store.apple.com/us/product/FC975LL/A Wondering which one to get. Im leaning towards the Regular Mac because of its upgradability, and the Retina only has 256 GB!!! shameful. Worried about the Retina's SOLDERED 8gb of ram running out for me. I will be using the computer for music production so i will upgrade the ram of the regular if i get it. I use Ableton Live 9. Which one would be better? P.S. almost forgot about ETHERNET!!
