Well I had a back to back with an iphone 4 and the N1, both on full brightness playing the same HD video (Top Gear). Iphone had its video encoded up to the max resolution you could play (I think 720p 30fps) and N1 had the same vid using rockplayer but at full 720p divx. Result is the N1 actually looked better than the retina display. Smoother, less pixelated and awesome. Rockplayer FTW.
