I probably feel its too large to be viewed anywhere, except as a wall mounted print that is at least a few feet wide. I like the panoramic format, but personally find anything beyond 3:1 a little unnaturally wide, at least with regards to standard/ single image presentation.
Just experimenting with PS Pano capabilities. Pretty impressed I have to say. I know what you mean though. I intend getting it printed. The size will depend on the cost
