There are still a bunch of little things about Windows that drive me crazy after using a Mac for so many years. On a Mac, when a text field is given intial focus, all the text is selected and when you hit the left arrow, it puts the focus at the beginning of the text field. On Windows, when you hit the left arrow, it moves the cursor one character from the far right. You have to hit Home to get to the beginning. Argh, drives me crazy!
