Thinking of buying a Macbook Pro. I'm wanting to run Windows XP via VMWare Fusion on it. I have a black Macbook at the moment (2.4GHz Intel Core 2 Duo, 2GB Ram) and it runs it pretty sluggishly, especially switching between the XP window and OSX. Would the base model Macbook Pro run it very well? Or should I get the one up from that (i7, 2.7GHz)? Or even the next one with quad-core - would the 'quad' make any difference in this case? Thanks, -Callum.
