我不负责任地猜测... :-)
不过还是有道理的：http://en.wikipedia.org/wiki/Motorola_Droid
Analytics firm Flurry estimated that 250,000 Motorola Droid phones were sold
in the United States during the phone's first week in stores.[20] Flurry
also estimated that 1.05 million Motorola Droids were sold in first 74 days
of the launch. This number is greater than that of the original iPhone which
sold one million units through day 74.
当时VZW没有iPhone也没有Android，只有Palm，Blackberry，还有Windows Mobile(?)
，有不少人因为iPhone转到AT&T去了。所以Droid出来的时候，VZW
大力推了一把，留住了不少用户。
