MacBookPro / MacBookAir performance question
With 4GB of RAM max, an Air would work, but you'd get tremendously better performance with 8GB in a Pro (ideally with an SSD).

I upgraded my Mid 2010 2.4GHz i5 to 8GB and an OWC 120GB SSD, and Windows (XP and 7) VMs under VMware Fusion 3 are much, much more responsive, along with the rest of the system.
