Hi All, With the new MBA release it is definitely exciting time. Unfortunately, I didn't get chance to sell mine in time to buy a new one. On the other hand, I went ahead and tried installing Lion on the late 2010 MBA. I followed few website to create installation DVD or USB drive, but for some reason the MBA will not recognize the USB nor the DVD at start up. I am trying to do a clean install. Any help? Thanks in advance!
