So with the lack of Gigabit ethernet options on the Macbook Air, I'm kinda hoping that some bright spark on here is going to shower me with suggestions on what 3rd party adaptors are available/been used...! I've had a real good hunt around, and the only adaptor which I can find that people have got excited about (back in 2009!) was the Buffalo one... Annoyingly, this is pretty much nowhere to be found... I'd really appreciate any suggestions from people here! The one thing stopping me from getting an MBA is the gig-e problem. As I use time-machine for backups, and transfer relatively large files around between offices<->datacentres<->home, it's rather important! Thanks in advance! A.
