Paul of MoDaCo recently picked up an Advent 4211 (MSI Wind variant) and has perfected installing OS X on the mini-notebook.  Paul has documented in great detail the entire process to get it working on the Advent for those who have a desire to do so.  He says it’s a very workable solution and that he really likes it.  Most everything is working under OS X but the deal breaker is the WiFi which won’t work.  Paul swapped the internal mini-PCI for another WiFi adapter so he worked around it.  He’s even got a video of the process so check it out!
