the 10 million (as a current iphone fan and user) is more than a flash in the pan. I just called verizon and they told me they've actually gotten a FEW calls abotu people trying to get the galaxy s4 after watching and seeing what ios7 looks like.
Me personally, I wait for the phone, not the OS system, but havign the iphone 5, and knowing the iphone 6 is without a doubt NEXT year.. and seeing this lackluster ios 7 today.. I'm not really impressed, and can see more people going with galaxy, or dare I say.. the Z10.
Especially knowing NOW the similarities between the galaxy s4's interface look and ios 7.. people might just say "o'll get the "bigger better device" as Samsung so loosely calls it
Strange I just called Verizon and they said they had a few calls about people asking how to return their S4 for an iPhone 5 after seeing the keynote.
Dont you love anecdotes??
