Riddle me this, if I use Google Play Music to, well, play music, and don't store it on-device, would I do alright with an 8GB? I mean...I have more than 16GB of music anyway and the downside to the Nexus for me is no expandable memory. But music on my phone is my main source of entertainment....if I use the cloud more than on-board memory, I should be A-OK with an 8GB yeah?
