I just saw someone recommend Virtual Box. Can anyone tell me a little more about it? Im interested in buying a MBA..... but currently i run Parallels on my White Macbook, and with less than 3MB of RAM it gets extremely slow. Im looking for alternatives and one of my concerns with the MBA is the RAM limit. I dont run anything else that requires more RAM, so im trying to come up with the best option possible for running Windows on my MBA. I appreciate all insight.
