MacBookPro / MacBookAir performance question I plan to replace my old MacBook with a new MacBookPro or Air but I am not exactly sure what I need. I work as a windows software developer so I need to run Windows with Visual Studio 2010. I am very sure this is no problem on any new machine and Bootcamp but I would like to run my windows only in a virtual machine. So I will be working with Visual Studio while still be able to use all the OSX tools the same time.

Is a MacBookAir powerful enough to do that?
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.
