Big no, especially with the need to be connected to the Iphone and the restriction of battery time.
If Dick Tracy could do this over 60 years ago Apple should be able by this time to get it right! ;-)
So let me get this straight. If I am a new guy to this Apple watch thing, I have to buy an iPhone, get a 2 year contract with a mobile service provider then by the watch? That sounds like a very steep investment.
