Google Explains Lack of SD Card Support For Nexus Devices
Google has explained that Nexus devices only offer fixed storage as the company wants to avoid "techy nonsense left over from the paleolithic era of computing".
Upon answering questions about the Nexus lineup on Google+, Google's director of user services on Android, Matias Duarte, said offering consumers expandable memory through SD cards was apparently too confusing.
"Everybody likes the idea of having an SD card, but in reality it's just confusing for users," he said. "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."
Instead of implementing SD card support, Nexus devices offers a fixed amount of space that "apps just seamlessly… use", with users not having to "worry about files or volumes or any of that techy nonsense left over from the paleolithic era of computing".
As for Jelly Bean's transition to consistent system buttons and status bars, Duarte explained that it's due to usability research and muscle memory. "What mattered most of all was muscle memory – keeping buttons where you expect them, no matter how you hold the device," Duarte explained.
Google recently announced the Nexus 4 smartphone (which won't feature LTE support), as well as the Nexus 10 tablet and a 3G 32GB variant of the Nexus 7.

can't you "Google" how to use SD cards on devices?

How do I move photos, videos or audio files back and forth ?
How do you unload stuff when you are on a trip and you filled up
the memory with pics and vids of the sight seeing trip or the recording of a business seminar?
Sorry, but without any means of external storage my wallet stays in my back pocket.
Windows xp warns me of degraded flash drive performance when I plug a USB 1.1 into a USB 2.0 port. Why can't Google do the same?
Apple? You really think they want some users upgrading their iPads' storage capacity cheaply?
Of course, I will save photos, videos on the card. It is easier to manage the data stored on the card. I don't need to restore the data after the reset or changing the phone.
Also, tit is more likely and easier to of retrieving the data if the phone is crushed or broken when the data is stored on the card.
If I buy the card with large capacity e.g. 32GB and it's not expensive nowaday, I hardly need to take the card out.
