I am currently using a mid-2010 MBP 13" which has a C2D 2.4GHz CPU. I upgraded the memory to 8GB and storage to SSD (160GB Intel X25-M). I mainly use this machine for virtualization with Fusion, often running several VMs for studying/lab purposes (but not really for production use). I've always wanted an Air, but the 4GB cap on memory (and lack of confidence in the CPU) prevented me from getting one. What really appeals to me is the extreme portability--the ability to fire up my VMs anywhere, anytime. Though my MBP has served me well in this regard, I've often found myself thinking "if I had an Air..." So the question is, assuming I could get 128-256GB storage and 8GB of memory with the new 11" model, would it perform on par with my current MBP? Would it perform better? I realize we can only speculate right now... Or, do any owners of the current 11" model who run Fusion have any experiences to share for reference?
