I'm purchasing a mac laptop for my mother. She doesn't need much horsepower so I was probably going to get her the base Macbook. The only issue is she needs Windows occasionally to do some web based work that requires Internet Explorer (very unfortunate). Do you think she could get away with the 32 bit version of Win7 with 1gb RAM allocated in Fusion? I realize 2GB of RAM is cheap but if it's not needed, OS X with 2gb RAM will be fine for the rest of her usage.
