One other key tidbit was just added to the Mercury article about Steve Jobs showing up at the Apple Store. Tech Analyst Gene Munster over at Piper Jaffray, believes that 600,000 to 700,000 were sold today alone. Earlier, he believed 300,000 would be sold over the entire weekend. As a point of reference, 270,000 iPhones were sold in its opening weekend. [SJ Mercury]
