Just wanted to share how well the Monoprice USB 2 gigabit ethernet adapter works on the new MacBook Air. It costs only $20. The speed I get is 30Mbyte/s over my wired home network. Here is the link: http://www.monoprice.com/products/p...=10311&cs_id=1031102&p_id=5345&seq=1&format=2 For Mac OS X, you must use the drivers on the enclosed mini-CD as the default Apple ones do not work. For Bootcamp/Windows 7, download from www.axis.com.tw, the chip manufacturer. Works great and much faster than Apple's fast Ethernet adapter or WLAN.
