Has anyone tried this yet? Please post your experiences with external displays. I am contemplating an upgrade from my 2.2 / 4G MBP with 128M VRAM, as i find that it often chokes on simpliest HD movie files created with a DSLR (weekish video), regardless whether I use it with or without the 30 inch Cinema display. So, I am curious how the new Air will run an external monitor, and whether it has enough juice to at least display the HD movies shot with a DSLR without dropped frames/jerkiness. (I guess I am asking two questions in one). Thanks in advance and happy holidays!
