iPad heater

Today has been interesting... Originally scheduled to be in meetings (not very demanding for an iPad) that have since been cancelled, I have been pushing the iPad rather harder.... Remote desktop sessions in particular.After 7 hours of non-stop use i have been noticing that the screen seems rather hot....something that I realised when a tiny crumb of dairy milk chocolate dropped on the screen and melted almost instantly!On the plus side, I have realised just how effective charging the iPad from completely flat using and iPhone charger rather than iPad charger - after 7 hours non-stop use AND listening to music on it earlier on the flight to London, it still has 78% battery. By start comparison, another employee here has a brand new Sony Vaio laptop which he had to plug in after 2 1/2 hours.....
