I wonder if the sdcard tray will pop out often by accident when the device is in use; like in a pocket of my trousers.

I think once a sdcard is inserted you do not change the sdcard often. I would put my whole music library on the card. Is there a mechanism to hold the sdcard in place? A security measure? Especially when you can use USB to transfer data on the device, I would guess that I need only to change the sdcard once in the lifetime of the tangara.

Heya, thanks for the question! We've designed the tray to be quite thin to prevent it from accidentally being pressed in, and it sits slightly shy of the case itself, so jostling in a pocket should be fine. You normally have to push the tray in quite a bit to get it to release.

I find I add new music often enough that having the sd card be easily accessible is ideal for me, but we encourage you to tinker with your devices to make them work for you. If you really wanted the additional security, you could use the open hardware files to design a new tray with an extra locking mechanism, or design a plug to replace the tray entirely and just cover the slot. In fact, I've already seen somebody design a case for Tangara with a sliding door to access the sd card instead of a tray.
