I am on the way back from the show which was in New York and am amazed at how easy it is to accidentally send emails on an iPad while on the train. My pinky has inadvertently hit the Send button three times today causing all sorts of problems.
For new emails I have decided to enter the address last - this is just part of the interesting behavioral changes Apple users have to make. I know people who type differently to avoid word replacements on iPhones. I suppose all products require compromises of one kind or another.
