I do just the opposite. I find it harder to type in all caps. I think it goes back to my typing class. I can't stop hitting the shift key when I start a sentence or go to the next field, so I get a lower case letter with all caps behind it and it looks really funky and I have to go back and correct. It is a muscle memory thing with me.
I don't mind all caps in returns...it is not a big deal for me, I just don't do it for the reason above.
