Android director of user services Matias Duarte said that the web giant's flagship products do not offer expandable memory for the sake of simplicity.
He wrote on Google+: "Everybody likes the idea of having an SD card, but in reality it's just confusing for users.
"If you're saving photos, videos or music, where does it go? Is it on your phone? Or on your card? Should there be a setting? Prompt every time? What happens to the experience when you swap out the card? It's just too complicated."
Duarte went on to say that Google aims to help users avoid the "techy nonsense left over from the paleolithic era of computing" with its user-friendly Nexus products.
Earlier this week, Google unveiled the Nexus 4 smartphone and the Nexus 10 tablet, as well as refreshing its Nexus 7 line with the launch of 32GB and 3G-supporting models.
