Have the Oct 2010 MBA 13". Been wanting to upgrade my 4yo iMac to something with an i5 or i7 chip. Waiting to see what happens with the next MBA or Mac mini - going to leave ALL options open till these are updated. In the mean time I was thinking that I would like to use the above MBA as a "media center" for my ATV2. My thoughts are to connect a 1.5 to 2TB HDD to it with my iTunes library and connect the MBA to my HDTV in a closed position. But not sure how this works since the MBA goes to sleep when the lid is closed.
