Would just like to add a shout out request. During recent conventions more people have been taking to using iPads to take photos during the guest talks (whether this has been commented about elsewhere I don't know). I understand some people may not have digital cameras but please, realise how big an iPad is and for the folk sat behind them. Quite a few times I found myself having to go through an entire talk staring through the camera screen on one as it blocked the entire stage.
Just a comment guys.
Please be courteous of others.
Thanks
