I'm really excited about the N8's HDMI port. This port is one of many things that helps earn the N8 the title of 'multimedia monster'. The people at Knowyourcell have uploaded a short video showing the N8 outputting a 720p movie trailer to a HD TV via HDMI.
This is what I've been looking for since I got my N95 so long ago: a portable movie player. My i8910 comes very close, but falls down when it comes to TV output. I can't W8 for the N8.
