Umm go read my post it pretty examplain with math why your entire argument fell apart. 500k in one day while impressive really does not mean much over all because it is Apple which means you get all the fans and built up hype in a quick buy but other than that not much.
Also you have to remember is just starting to offer some good android phones. Before really now they had 1 good android power phone by the end of the 1Q AT&T will have I believe 4 fairly good android power phones and the Galaxy 2 I believe is going to be talked about this week at MWC.
And I explained why your math was wrong, since the combined sales of the iPhones not including Verizon and the Verizon iPhones themselves exceeded, for one day at least, 750,000 units and likely will exceed global Android sales--at least for a while until the Verizon market settles down. This, of course, assumes Verizon themselves don't end up 'screwing the pooch', as they say--something I've already read about happening within the first two weeks of Verizon's marketing and service for the iPhone.
