I am intrigued about the new Z10, but not sure if I am intrigued enough to get one.
I just learned last night that you can upload all the digital pictures that you ever took in your life for free to your Google+/Google Drive. There is no space limit as long as you upload at a max resolution of 2048pi. This is an example of just another amazing Google service that is free.
Apple has the cool Photo stream, iCloud, Airplay thing going for it.
At this point in time, nobody can touch these two companies when it comes to an all round smartphone ecosystem. There is very little incentive to go to the BlackBerry or the Windows Phone platform. Once the newness wears off of a new platform, the lack of features/services will start bugging you.
