Hello all. I just got my MBA and was wanting to know which is the least expensive Ethernet adapter. I realize that the Thunderbolt adapter for $29 that Apple sells is the best one, but $29 for something I will probably NEVER use.... Also I was reading that MOST USB Ethernet adapters don't work OOB with OS X Lion, so does anyone have one that will. It doesn't have to be gigabit, 100Mb wilb be fine as I will just throw the thing in the bag and probably never use it. Thanks.
