I'm not one that insist on using SL and think it's better than Lion or anything like that. What I do have is a need to dual boot my 2011 13" MBA with SL if at all possible in order to work on a technical problem for my job. I need SL in order to recreate the conditions of the problem so I can troubleshoot it from there and find a work around. I've been using SL in VMware Fusion thus far but am convinced that the way external port sharing happens with Fusion is basically causing me to have the same conditions that are specific to Lion. A co-worker in a different state has a older Mini with SL and can do what I'm trying to accomplish with my SL running in the VM so at this point I'm convinced I need to boot into a native SL instance. All that said, is there any clear and final answer if SL can or cannot be installed on this 2011 13" MBA? If it can, then is there a good guide on what needs to be done to make it happen?
