How about a custom keyboard with romantic messages or love quotes engraved on each keycap for your anniversary? That would make the keyboard very special and personalized for your wife. Depending on your budget and her preferences, you may want to look into mechanical keyboards or keyboard kits so that she can also customize the switches, keycaps, and layout to her liking.
