Hey folks, So I got the Macbook Air 13' basic a few days ago and a lot of people from what I've been reading from the forums suggest that if I am to use Windows 7, I need to have better specs, so I was thinking of bumping the memory to 4GB instead of the current 2GB. My question is, what changes would I notice? Will it boot faster? Graphics? I am not sure what to expect. Thank you.
