Looking to replace my 2.8 C2D MBP15 with a new MBA 13. I know the screen res is the same, but the smaller physical size has me worried for some reason. How do people find the screen on the MBA compared to the MBP? Anyone done the same? Thoughts? I could wait to see what Apple does with the next MBP/A 15" but really the new MBA are plenty computer for me and the smaller size is a nice plus.
