$399 USD is great, but why are we still stuck with 16 GB of storage on base model phones? You can barely put a day's worth of music on your phone and you cannot always stream via services like Spotify. Spotify accounts for 2 GB of traffic per month on my phone and some plans are barely affordable when you want more than that--fortunately I can do up to 6 GB before I am traffic shaped, but that isn't the say the same…
A full 24 hours worth of music (~33 complete albums) at 192 kbps is only 2GB.
Google Play Music has spoiled me -- their station selection is vast. Albums don't even mean anything to me.
Plus I can upload all of my personal music collection to it and listen to it on the go, and it exceeds 2GB easily.
