That is something I was told in the Apple store today. I am still working on my decision to switch and i made an appointment at the Apple store to learn more about the macbook. The guy was awesome and able to answer all my questions and do some terrific demos. I am almost there. He made an interesting statement to me. I told him that I may on occasionally need to run software that will only run on windows and this software is slow even on a windows machine. I was concerned about how fast it would run it I booted to windows through bootcamp and ran the software. He said it would run faster than on a windows machine because of the way the mac handles ram. He drew a little diagram of it and he sounded very credible but I had honestly never heard that before. Does this sound true? Very nice if it is.
