When you click on the Add button to add a speed dial, it would make much more sense to leave the cursor in the text box in edit mode (with the default text selected) This way after clicking on Add, you can immediately type the name of the person, then tab to the number. It would also be good to have Keyboard accelerators on the Add/Delete buttons ie Add delete etc so you press Alt-A for add, Alt-D for delete. Also, a toolbar icon to edit speed dials would be good, as would an edit option when you right-click on a speed dial. These are all just how people expect applications to behave. But it is still a great application.
