How about a personalized mechanical keyboard? You could select special keycaps with symbols or messages that have meaning to your wife, or choose a specific color or theme for the keyboard that she will love. There are many customizable options available online, and some even allow you to upload your own design to be printed onto the keyboard. You could also add a special touch by programming certain keys with special commands or messages that only you and your wife will understand.
Or you can get her a star map with the date of your first kiss.
