where is yahoo notepad when I use my mini?
There is no yahoo notepad for iOS. In your yahoo account settings, you can enable sync'ing of your yahoo notes - they will be sync'd with iOS notes application.
According to Yahoo, it is also a one way sync - see http://help.yahoo.com/kb/index?page=content&id=SLN3688&locale=en_US&y=PROD_MAIL_ ML
