My 17" powerbook screen cracked. I am going to get a MacBook Pro unibody, but am wondering about screen size... The 15" is more in my price range, but wondering if it is hard going from a 17" to a 15"? I do some web design and run a small business using 17", so I often have many screens opened at one time. I am often transferring information from one screen to another. Is this going to be frustrating trying to do this on a smaller screen?
