Wait... uploading your collection to Google Music is the same as cloud storage, right? Same as if you uploaded it to Amazon's cloud system or if you used iTunes Match.
But you should try GMusic. I know it's not official but I use it for my Google Music uploaded files and it works pretty well. It should at least get you by until an official app is released.
Google Music is a cloud locker for your music. Just like iTunes Match and Amazon. I opted for this service because it was free and it had a great Android app (music player).
GMusic was the best 3rd party Google Music app that I used on iOS. There are a few. But it failed at consistently downloading my music for offline use. It was just buggy as hell and not up to par. I would expect an official iOS Google Music app to remedy this. If that day ever comes.
I'm not planning on using an iPhone anytime soon so it's not exactly a huge issue for me right now. However if the time comes where Apple releases a larger iPhone, I do hope there is either an official Google Music app on iOS or a 3rd party alternative that is great and downloading your music for offline use. This is important to me as I don't have unlimited data.
I just got a chance to handle the 5C/5S in person for the first time. The white 5C reminds me a lot of the white 3G/3GS, just smaller and lighter of course. I like the look of the white model and if forced to pick one, I'd grab that version.
I hate the other colors. I think Apple should have made at least one black model for the 5C. Perhaps a dark brown too.
I read in a review that the 5C bottom speaker is inferior to the 5/5S's. Not sure why more publications aren't talking about this in their reviews.
The space grey 5S isn't as nice as the slate/black 5 IMO. I get why they ditched the slate model (anodizing issues left scuffs).
I've been using the S4 Active since it launched and I have to say that using a 4" screen today was a nightmare. I put both side by side and I was forced to keep the 4" screen much closer to my face to read things on the web clearly. I will never, ever, go back to a 4" screen. I think my sweet spot is 4.7"-5". I would be very tempted by an iPhone 6 with a screen of this size.
