I recently took possession of a mid-2012 13" MBA. Loving it. Wonderful. Only one problem I'm hoping I can get advice from you all about. My employer is unlikely to pony up for TB Monitor from Apple. Something about the $999 price tag... Unfortunately if use the TB port on my MBA for a non-TB Monitor, I lose my ability to use it for my ethernet connection (wireless in my office is not reliable). I'm hoping for a recommendation for an external monitor that I could run off one of the two USB 3 outputs on the MBA. Does any one have experience with this or recommendations?
