What do you all think of this plan to get around the Google Music caching issue:
I currently link the Google Music uploader on my PC to my iTunes library and stream most of my music from my Play library in the cloud. I figured I would just use Samsung Kies and point it to my iTunes music folder instead and let it sync to the SD card (I ordered the 64GB SDXC one from Sandisk for $25 via Amazon Warehouse Deals). It can sync wirelessly via WiFi so that's a nice plus.
So with this setup I can use whatever music player I want, sync it with my iTunes library wirelessly, and not have to worry about what is in the cloud or on the device since it's all going on the SD card. This would make me feel a little better about the 16GB model.
