Hi, I want to buy the new Macbook Retina. It seems the perfect device for me (size, fit and finish, weight etc.) My question: How well does the 1.2Ghz (or 1.3GHz) model handle virtualization. I need 2 or 3 smaller linux development environments on my machine, each has maybe 512mb or 1gb of RAM attached. I am using Virtualbox. Do you have experience with this?
