Mr. munster says that the u.s. likely contributes about a third of apple 's overall iphone sales , with the rest coming from overseas .

蒙斯特说，iphone的整体销量中，美国市场可能占了大约三分之一，其余都来自国外市场。

As a result , " launch figures are not a perfect apples-to-apples comparison " , gene munster , a piper jaffray analyst , wrote to clients on monday .

因此，“首发销量不是苹果产品之间比较的完美指标，”piperjaffray分析师基尼？蒙斯特（genemunster）周一在给客户的信中写道。

That looks great , but munster argues that it should have been a layup seeing as the comparison was with the first quarter of 2009 , when the economy was in the toilet .

这看起来相当不错，但穆斯特称，与2009年第一季度相比，同比增长应有直线上升，因去年一季度经济一团糟。
