I think you guys are being a bit harsh on atco-matic. Maybe he has to sleep. There have been a couple of times I have Done JFK-LHR where I have left the US office 4PM EST to be in the UK office 9AM GMT and its difficult to do 2 days work without sleep between them.
It does appear that the majority here are keen on the blinds open but considering the nature of this site that is only to be expected. I have been in BA business class from SEA-LHR with no one in the compartment intrested in the blinds being open and almost all asleep.
Having said that I did not need to go to work after the SEA-LHR flight so ended up sat on the floor by the main door looking out the window and chatting to the stewardesses as I like looking out too - problem solved.
