I tried this last night at the Apple Store on an 1.4GHz 11.6 MBA with 2GB Ram. It did quite well at 1080p full screen, but I'm not certain if it was encoded properly as the video seems a little choppy on my 13" MB.
When I launched two windows with two videos going simultaneously on the MBA, it had significant problems: lags and start/stops. It might be an issue with the limited RAM of the in-store models.
Out of curiosity, I ran speedtest.net which revealed the store WiFi network was 30MB both up and down. So there wasn't any factors due to the download.
